Organometallic pi-tweezers, NCN pincers, and ferrocenes as molecular “Tinkertoys” in the synthesis of multiheterometallic transition-metal complexes

This review describes the synthesis, reaction chemistry, structures, and bonding of early-late heterodi-, heterotri-, and heterotetrametallic transition-metal complexes by applying the molecular “Tinkertoy” approach. As connecting units between the different metal atoms, pi-conjugated carbon-rich organic and/or inorganic groups can be used. The electrochemical behavior of such one-dimensional molecular wire molecules, coordination polymers, starlike structures, and dendritic oriented transition-metal species, respectively, is presented as well.

Development of a ruthenium multi-pyridine complex as photosensitizer for highly efficient light driven water oxidation

As we all know, the photosensitizer is the vital role in photocatalytic water oxidation system. In this paper, a novel [Ru(bpy)2(tpphz)](PF6)2 complex (PS1) was synthesized and characterized fully. And, it displayed a higher photoactivity (TON, 110) than [Ru(bpy)3](PF6)2 (PS2) (TON, 62) and [Ru(bpy)2(dcb)](PF6)2 (PS3) (TON, 82) for water oxidation in a three-component system with Ru(bda)(isoq)2 as catalyst. The main reason for the enhancement of photocatalytic activity should be that the pi-pi stacking supramolecular interaction between the pi-tpphz ligand of the PS1 and the pi-isoq ligand of the catalyst increased the intermolecular interaction between PS1 and catalyst, and promoted the molecular aggregation and accelerated valid electronic transmission. Nevertheless, a modest driving force of PS1 for photocatalysis water oxidation should be another contribution.

Pyridylphosphinate metal complexes: Synthesis, structural characterisation and biological activity

For the first time, a series of 25 pseudo-octahedral pyridylphosphinate metal complexes (Ru, Os, Rh, Ir) has been synthesised and assessed in biological systems. Each metal complex incorporates a pyridylphosphinate ligand, a monodentate halide and a capping eta6-bound aromatic ligand. Solid- and solution-state analyses of two complexes reveal a structural preference for one of a possible two diastereomers. The metal chlorides hydrolyse rapidly in D2O to form a 1:1 equilibrium ratio between the aqua and chloride adducts. The pKa of the aqua adduct depends upon the pyridyl substituent and the metal but has little dependence upon the phosphinate R? group. Toxicity was measured in vitro against non-small cell lung carcinoma H460 cells, with the most potent complexes reporting IC50 values around 50 muM. Binding studies with selected amino acids and nucleobases provide a rationale for the variation in toxicity observed within the series. Finally, an investigation into the ability of the chelating amino acid l-His to displace the phosphinate O-metal bond shows the potential for phosphinate complexes to act as prodrugs that can be activated in the intracellular environment.

Arene ruthenium complexes as versatile catalysts in water in both transfer hydrogenation of ketones and oxidation of alcohols. Selective deuterium labeling of rac-1-phenylethanol

The preparation of three series of arene Ru(II) half-sandwich compounds with the functional ligand 4,4?-dimethoxy-2,2?-bipyridine (dmobpy) is described. The new cationic derivatives have the general formula [(eta6-arene)RuCl(kappa2-N,N-dmobpy)]X (arene = benzene, X = Cl- ([1]Cl), BF4- ([1][BF 4]), TsO- ([1]TsO), PF6- ([1][PF6]); arene = p-cymene (p-cym), X = Cl- ([2]Cl), BF4- ([2][BF4]), TsO- ([2]TsO), PF6- ([2][PF6]); arene = 2-phenoxy-1-ethanol (phoxet), X = Cl- ([3]Cl), BF4- ([3][BF 4]), TsO- ([3]TsO), PF6- ([3][PF6])). The structures of [1]Cl, [1]TsO, [2]TsO, [2][BF 4], and [2][PF6] were determined by X-ray crystallography. All of the complexes except the PF6- salts were water-soluble, and they behaved as active catalysts in two different processes: the transfer hydrogenation of water-soluble and -insoluble ketones to the corresponding alcohols, using HCOONa as the hydrogen source at pH 4, and the oxidation of rac-1-phenylethanol to acetophenone with tBuOOH at pH 7, both in aqueous solution. For the transfer hydrogenation with p-cymene complexes the aqua, formato, and hydride species were detected by means of 1H NMR experiments in D2O. It was found that the cationic hydrido complex was [(eta6-p-cymene)RuD(dmobpy)]+. The reversible and pH-dependent formation of the hydroxo derivative was also observed. When the catalytic transfer hydrogenation was performed in D 2O, the 1-phenylethanol obtained was selectively deuterated at the benzylic carbon. Mechanistic proposals are also included.

Turning on red and near-infrared phosphorescence in octahedral complexes with metalated quinones

We report the synthesis of pi-bonded ruthenium, rhodium, and iridium o-benzoquinones [Cp*M(o-C6H4O2)] n [M = Ru (2), n = 1-; Rh (3), n = 0; Ir (4), n = 0] following a novel synthetic procedure. Compounds 2-4 were fully characterized by spectroscopic methods and used as chelating organometallic linkers, “OM-linkers”, toward luminophore bricks such as Ru(bpy) 22+, Rh(ppy)2+, and Ir(ppy) 2+ (bpy = 2,2?-bipyridine; ppy = 2-phenylpyridine) for the design of a novel family of octahedral bimetallic complexes of the general formula [(L-L)2M(OM-linkers)][X]m (X = counteranion; m = 0, 1, 2) whose luminescent properties depend on the choice of the OM-linker and the luminophore brick. Thus, dinuclear assemblies such as [(bpy)2Ru(2)][OTf] (5-OTf), [(bpy)2Ru(2)][Delta- TRISPHAT] (5-DeltaT) {TRISPHAT = tris[tetrachlorobenzene-1,2-bis(olato)] phosphate}, [(bpy)2Ru(3)][OTf]2 (6-OTf), [(bpy) 2Ru(4)][OTf]2 (7-OTf), [(bpy)2Ru(4)][Delta- TRISPHAT]2 (7-DeltaT), [(ppy)2Rh(2)] (8), [(ppy) 2Rh(3)][OTf] (9-OTf), [(ppy)2Rh(4)][OTf] (10-OTf), [(ppy)2Rh(4)][Delta-TRISPHAT] (10-DeltaT), [(ppy) 2Ir(2)] (11), [(ppy)2Ir(3)][OTf] (12-OTf), [(ppy) 2Ir(4)][OTf] (13-OTf), and [(ppy)2Ir(4)][Delta-TRISPHAT] (13-DeltaT) were prepared and fully characterized. The X-ray molecular structures of three of them, i.e., 5-OTf, 8, and 11, were determined. The structures displayed a main feature: for instance, the two oxygen centers of the OM-linker [Cp*Ru(o-C6H4O2)]- (2) chelate the octahedral chromophore metal center, whether it be ruthenium, rhodium, or iridium. Further, the carbocycle of the OM-linker 2 adopts a eta4-quinone form but with some catecholate contribution due to metal coordination. All of these binuclear assemblies showed a wide absorption window that tailed into the near-IR (NIR) region, in particular in the case of the binuclear ruthenium complex 5-OTf with the anionic OM-linker 2. The latter feature is no doubt related to the effect of the OM-linker, which lights up the luminescence in these homo- and heterobinuclear compounds, while no effect has been observed on the UV-visible and emission properties because of the counteranion, whether it be triflate (OTf) or Delta-TRISPHAT. At low temperature, all of these compounds become luminescent; remarkably, the o-quinonoid linkers [Cp*M(o-C6H4O2)] n (2-4) turn on red and NIR phosphorescence in the binuclear octahedral species 5-7. This trend was even more observable when the ruthenium OM-linker 2 was employed. These assemblies hold promise as NIR luminescent materials, in contrast to those made from organic 1,2-dioxolene ligands that conversely are not emissive.

Diaminohexopyranosides as ligands in half-sandwich ruthenium(II), rhodium(III), and iridium(III) complexes

The syntheses of methyl 2,3-diamino-4,6-O-benzylidene-2,3-dideoxy-alpha-d-hexopyranosides of glucose, mannose, gulose, and talose and methyl 2-amino-4,6-benzylidene-2,3-dideoxy-3-tosylamido-alpha-d-glucopyranoside are exhaustively presented, as well as their application as ligands in half-sandwich ruthenium(II), rhodium(III), and iridium(III) complexes. The complex formation occurs highly diastereoselectively, creating a stereogenic metal center. The molecular structures of the ligands and their complexes were investigated by X-ray structure analysis, NMR spectroscopy, polarimetry, and DFT methods. The diamino monosaccharide complexes have been subjected to antitumor activity studies. In vitro tests of a few ruthenium complexes against different cancer cell types showed antiproliferative activities 4-10 times lower than that of cisplatin.

New luminescent probe for the selective detection of dopamine based on in situ prepared Ru(II) complex-sodium dodecyl benzyl sulfonate assembly

Due to clinical importance, detection of dopamine by using easy and rapid method is still ongoing challenge. Here we present a simple and quite efficient method for dopamine (DA) detection in alkalescent medium using in situ prepared Ru(II) complex and sodium dodecyl benzyl sulfonate (SDBS) as highly luminescent luminophore. The luminescence enhancement in the Ru(II) complex (Ru-CIP) has been observed in the miceller medium formed by SDBS. The capability to successively quench the luminescence intensity has been tested for variety of molecules and only dopamine as analyte found to be able to quench luminescence effectively. Hence selective quenching of luminescence by dopamine was used as a tool to detect dopamine and two linear concentration ranges has been established from 0.1 muM to 1muM and from 2 muM to 10 muM with limit of detection (LOD) is 6.6 nM (S/N = 3). Spectral evidence showed that luminescence quenching mechanism arose via Forster resonance energy transfer (FRET) among oxidized DA (i.e. DA quinone) and in situ generated Ru-CIP and SDBS assembly. Due to ultra sensitivity and high selectivity of the prescribed (Ru-CIP-SDBS) luminescent probe has a strong potential for practical analytical application in clinical diagnosis.

Synthesis, characterization, redox behavior, DNA and protein binding and antibacterial activity studies of ruthenium(II) complexes of bidentate schiff bases

Two new ruthenium(II) complexes of Schiff base ligands (L) derived from cinnamaldehyde and ethylenediamine formulated as [Ru(L)(bpy)2](ClO4)2, where L1 = N,N?-bis(4-nitrocinnamald-ehyde)ethylenediamine and L2 = N,N?-bis(2-nitrocinnamaldehyde)-ethylenediamine for complex 1 and 2, respectively, were isolated in pure form. The complexes were characterized by physicochemical and spectroscopic methods. The electrochemical behavior of the complexes showed the Ru(III)/Ru(II) couple at different potentials with quasi-reversible voltammograms. The interaction of the complexes with calf thymus DNA (CT-DNA) using absorption, emission spectral studies and electrochemical techniques have been used to determine the binding constant, Kb and the linear Stern?Volmer quenching constant, KSV. The results indicate that the ruthenium(II) complexes interact with CT-DNA strongly in a groove binding mode. The interactions of bovine serum albumin (BSA) with the complexes were also investigated with the help of absorption and fluorescence spectroscopy tools. Absorption spectroscopy proved the formation of a ground state BSA-[Ru(L)(bpy)2](ClO4)2 complex. The antibacterial study showed that the Ru(II) complexes (1 and 2) have better activity than the standard antibiotics but weak activity than the ligands.

Role of the Trichlorostannyl Ligand in Tin?Ruthenium Arene Complexes: Experimental and Computational Studies

A set of neutral and ionic ruthenium arene trichlorostannyl complexes are reported herein. The tin(II) compounds L1SnCl {1; L1 = [2-(CH2NEt2)-4,6-(tBu)2C6H2]?} and [L2SnCl][SnCl3] {2; L2 = 2,6-[(CH3)C=N(C6H3-2,6-iPr2)2]C5H3N} showed a rather different reactivity towards the ruthenium complex [(eta6-cymene)RuCl]2(eta-Cl)2. As a consequence, the neutral complex [Ru(eta6-cymene)(L1SnCl)Cl2] (4) and the ionic compound [L2SnCl][Ru(eta6-cymene)(SnCl3)2Cl] (8) were isolated. The insertion reaction of 4 with SnCl2 provided the neutral trimetallic ruthenium complex [Ru(eta6-cymene)(L1SnCl)(SnCl3)Cl] (6). Analogous ruthenium complexes [Ru(eta6-cymene)(L3PPh2)Cl2] (5) and [Ru(eta6-cymene)(L3PPh2)(SnCl3)Cl] (7) containing the phosphane ligand L3PPh2 {3; L3 = [2,6-iPr2-(C6H3)NH]?} were also prepared to evaluate the donor?acceptor strength of the tin(II)- and phosphorus-containing ligands. The structural characterization and DFT calculations of the above-mentioned complexes suggest a strong influence of the [SnCl3]? moiety on the Ru?E interaction (E = Sn, P). The influence of the trichlorostannyl ligand on the Ru?E interaction in the complexes 4?7 was further evaluated by means of a distortion/interaction analysis.
