[RuCl(arene)(mu-Cl)]2 dimers were treated in a 1:2 molar ratio with sodium or thallium salts of bis- and tris(pyrazolyl)borate ligands [Na(Bp Br 3)], [Tl(Tp Br 3)], and [Tl(TpiPr, 4Br)]. Mononuclear neutral complexes [RuCl(arene)(kappa2-Bp Br 3)] (1: arene=p-cymene (cym); 2: arene=hexamethylbenzene (hmb); 3: arene=benzene (bz)), [RuCl(arene) (kappa2-Tp Br 3)] (4: arene=cym; 6: arene=bz), and [RuCl(arene)(kappa2-TpiPr, 4Br)] (7: arene=cym, 8: arene=hmb, 9: arene=bz) have been always obtained with the exception of the ionic [Ru2(hmb)2(mu-Cl)3][Tp Br 3] (5?), which formed independently of the ratio of reactants and reaction conditions employed. The ionic [Ru(CH3OH)(cym)(kappa2-Bp Br 3)][X] (10: X=PF6, 12: X=O3SCF3) and the neutral [Ru(O2CCF3)(cym)(kappa2-Bp Br 3)] (11) have been obtained by a metathesis reaction with corresponding silver salts. All complexes 1-12 have been characterized by analytical and spectroscopic data (IR, ESI-MS, 1H and 13C NMR spectroscopy). The structures of the thallium and calcium derivatives of ligand Tp Br 3, [Tl(Tp Br 3)] and [Ca(dmso)6][Tp Br 3]2×2 DMSO, of the complexes 1, 4, 5?, 6, 11, and of the decomposition product [RuCl(cym)(HpziPr, 4Br)2][Cl] (7?) have been confirmed by using single-crystal X-ray diffraction. Electrochemical studies showed that 1-9 and 11 undergo a single-electron RuII?Ru III oxidation at a potential, measured by cyclic voltammetry, which allows comparison of the electron-donor characters of the bis- and tris(pyrazol-1-yl)borate and arene ligands, and to estimate, for the first time, the values of the Lever EL ligand parameter for Bp Br 3, Tp Br 3, and TpiPr, 4Br. Theoretical calculations at the DFT level indicated that both oxidation and reduction of the Ru complexes under study are mostly metal-centered with some involvement of the chloride ligand in the former case, and also demonstrated that the experimental isolation of the mu3-binuclear complex 5? (instead of the mononuclear 5) is accounted for by the low thermodynamic stability of the latter species due to steric reasons.

Two new ruthenium(II) complexes of formula [Ru(bpy)2-(L 1)][PF6] and [Ru(bpy)2(L2)][PF 6]2 are reported. HL1 is a (nitrophenyl) ethenyl-substituted phenylpyridine ligand, and L2 is the bipyridine analogue of HL1. The X-ray crystal structure of [Ru(bpy) 2(L1)][PF6] has been solved, and the compound is found to crystallize in the monoclinic C2/c space group. The electronic spectrum of the cyclometalated derivative [Ru(bpy)2(L 1)][PF6] exhibits a low-lying transition that is red-shifted from 454 to 546 nm relative to that of the parent bipyridine-based complex, which reveals an important charge-transfer character. To support this assumption, the nonlinear optical properties were investigated by the hyper-Rayleigh scattering technique and indicate a molecular static hyperpolarizability (beta0) equal to 230 × 10-30 cm5 esu-1.

Over the past 20 years, ruthenium(II)-based dyes have played a pivotal role in turning dye-sensitized solar cells (DSCs) into a mature technology for the third generation of photovoltaics. However, the classic I3-/I- redox couple limits the performance and application of this technique. Simply replacing the iodine-based redox couple by new types like cobalt(3+/2+) complexes was not successful because of the poor compatibility between the ruthenium(II) sensitizer and the cobalt redox species. To address this problem and achieve higher power conversion efficiencies (PCEs), we introduce here six new cyclometalated ruthenium(II)-based dyes developed through ligand engineering. We tested DSCs employing these ruthenium(II) complexes and achieved PCEs of up to 9.4% using cobalt(3+/2+)-based electrolytes, which is the record efficiency to date featuring a ruthenium-based dye. In view of the complicated liquid DSC system, the disagreement found between different characterizations enlightens us about the importance of the sensitizer loading on TiO2, which is a subtle but equally important factor in the electronic properties of the sensitizers.

The cis-[Ru(bpy)2(4-bzpy)(NO)](PF6)3 complex was prepared (4-bzpy = 4-benzoylpyridine), and characterized by UV-visible, infrared and nuclear magnetic resonance (NMR) spectroscopies and electrochemical techniques. The reaction with cysteine was preliminarily investigated, aiming to shed light on the potential biological mechanism for NO or HNO release mediated by thiols. Furthermore, photochemical behavior of cis-[Ru(bpy)2(4-bzpy)(NO)](PF6)3 was studied, where it was observed NO release upon ultraviolet, blue and green light irradiations. This latter long wavelength showed still good efficiency, which has not been reported for this type of complex. This feature is very important for a potential application in phototherapy. Additionally, vasorelaxant activity was investigated in rat-isolated aorta. This compound exhibited a greater maximum efficacy than sodium nitroprusside (SNP) as a blood vessel relaxant. Nevertheless, the EC50 for SNP (13.3 nmol L-1) was 52-fold smaller than the EC50 for cis-[Ru(bpy)2(4-bzpy)NO](PF6)3 (690 nmol L-1). Altogether, these results suggest this complex is a promising NO donor agent deserving further biological studies.

Reference of 37366-09-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer. In a document type is Article, introducing its new discovery.

Highly conjugated perinones were evaluated as proligands with [Ru(eta6-arene)Cl2]2 precursors (arene = p-cymene or benzene). None of them, except itaco-perinone (IP) bearing one exocyclic methylene group, were able to form coordination compounds. Expected eta1-coordination through the lone pair of the nitrogen or oxygen atoms of the perinone did not occur. Instead a deprotonation reaction involving the exocyclic methylene was observed and the corresponding [Ru(eta6-arene)(eta3-IP)Cl] complex was isolated in moderate yields. Mechanistic studies revealed that the base-promoted isomerization of itaco-perinone to citraco-perinone prevented higher yields in the synthesis of the allylic complexes. Additionally, it was observed that IP can dimerize through the exocyclic methylene group, indicating high reactivity of this carbon?carbon double bond. Electronic absorption and emission properties of the perinones and organometallic compounds were studied.

2,2?-Dipyridylamine (dpa) derivatives carrying a thiol-targeted maleimide group located at the end of an alkyl substituent on the central amine were synthesized. Reaction with the organometallic precursors [(eta6-arene)RuCl2]2 (arene = benzene or p-cymene) yielded the half-sandwich cationic complexes [(eta6-arene)Ru(dpa)Cl]+ where the dipyridylamine derivatives were coordinated as bidentate N,N donor ligands. Enzymatic studies showed that these derivatives were able to inactivate the cysteine endoproteinase papain by S-alkylation of the cysteine active site.
