Hydrous ruthenium oxide-coated titanium electrodes (RuOx·nH2O/Ti) with high pseudocapacitance were prepared by cyclic voltammetry from an aqueous chloride solution in the -200 to 1000 mV range. The growth rate of RuOx·nH2O, represented by ip (peak current) of the cyclic voltammograms, was constant up to cycle 120, but it decreased slightly between 120 and 240 cycles. Voltammetric responses studied by cyclic voltammetry as well as the charging and discharging behavior examined by chronopotentiometry in 0.5 M H2SO4 demonstrated the suitability of RuOx·H2O for use in electrochemical capacitors. X-ray diffraction spectra exhibited an amorphous structure of this hydrous oxide film. The oxide consisted of mixed oxyruthenium species with various oxidation states as demonstrated by X-ray photoelectron spectroscopy, and the RuOx·nH2O surface showed a porous morphology.

Ruthenium (II) complexes of the type cis-Ru(H2dcbiq)2X2 and cis-Ru(H2dcdhph)2X2, where H2dcbiq = 4,4?-dicarboxy-2,2?-biquinoline, H2dcdhph = 5,8-dicarboxy-6,7-dihydro-dibenzo[1,10]-phenanthroline, and X = Cl-, NCS- or CN-, have been synthesized and spectroscopically characterized. The resulting complexes show a broad and intense metal-to-ligand charge transfer (MLCT) band in the visible region with a peak between 580 and 700 nm and are emissive at room temperature. The ground-state first pKa value of cis-Ru(H2dcbiq)2(NCS)2 (2) was determined to be 2.9 by the spectrophotometric method. Photoelectrochemical measurements show that all dyes, when anchored to a nanocrystalline TiO2 film electrode, present low light-harvesting efficiencies due to inefficient driving force for electron injection into the conduction band of TiO2 from their lower energy MLCT band. The photoelectrochemical performance of 2 was also investigated on a number of oxide semiconductor thin films such as Nb2O5, ZnO, SnO2 and In2O3. The results show that a high value of short-circuit photocurrent (Jsc) is observed for the semiconductors having a low-energy conduction band potential (SnO2 and In2O3). In the dye 2-sensitized TiO2 film, the absorbed photon-to-current conversion efficiency (APCE) spectrum shows an absorption band selective electron injection yield, while a wavelength independent electron injection yield is observed when dye 2 is anchored to SnO2. These results indicate that the lowest excited MLCT state is energetically favorable for electron injection into the conduction band of SnO2 but not for TiO2.

10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 10049-08-8, SDS of cas: 10049-08-8

Compounds of the type [Ru(tpy)(L2)(dmso)]z+ (tpy is 2,2?:6?,2?-terpyridine; L2 can be 2,2?-bipyridine (bpy), N,N,N?,N?-tetramethylethylenediamine (tmen), 2-pyridine carboxylate (pic), acetylacetonate (acac), malonate (mal), or oxalate (ox)) have been studied by X-ray crystallography, electrochemistry, NMR, IR, and UV-vis spectroscopy. When L2 is bpy, tmen, or pic, the dmso ligand can be intramolecularly isomerized either electrochemically or photochemically. Isomerization is not observed when L2 is acac, mal, or ox. Isomerization results in a drastic change in the absorption spectrum, as well as in the voltammetry. Absorption maxima shift by 3470 (419-490 nm), 4775 (421-527 nm), and 4440 cm-1 (429-530 nm) for the bpy, pic, and tmen complexes, respectively. Reduction potentials for S-bonded and O-bonded complexes differ by 0.57, 0.75, and 0.62 V for the bpy, pic, and tmen complexes, respectively. Quantum yields of isomerization (phiS?O) were determined for the bpy (0.024 ± 1), pic (0.25 ± 1), and tmen (0.007 ± 1) complexes. In comparison of these data to photosubstitution quantum yields, it appears that the isomerization mechanism does not involve the ligand field states. This result is surprising given the importance of these states in the photochemistry of ruthenium and osmium polypyridine complexes. These results and details of the mechanism are discussed.

Black crystals of the bismuth subchloride Bi7Cl10 were obtained by slow cooling of stoichiometric mixtures of Bi und BiCl 3 from 500C to ambient temperature. By means of thermal analyses the phase diagram Bi/BiCl3 was specified. Bi7Cl 10 decomposes peritectoidally into Bi6Cl7 and BiCl3 at 190 ± 5C. The phase barogram of the binary system was determined by total pressure measurements in the membrane zero-manometer. From the pressure functions of the bismuth chlorides as well as from measurements of the molar heat of Bi6Cl7 the thermodynamic standard data were derived: DeltaHB(Bi 6Cl7, 298) = -895 ± 5 kJ·mol-1; S(Bi6Cl7, 298) = 620 ± 10 J·mol -1 K-1; DeltaHB(Bi7Cl 10, 298) = -1310 ± 10 kJ·mol-1; S(Bi7Cl10, 298) = 730 ± 20 J·mol -1 K-1. Using these data, thermodynamic modelling of the solid-gas-equilibria were carried out in order to optimize the synthesis of Bi7Cl10. The phase-pure vapour deposition of Bi 7Cl10 is impossible due to the condensation of the dominating gas-species in the stability range of the compound. X-ray diffraction on single-crystals at room temperature revealed that Bi7Cl 10 crystallizes with the tetragonal space group I 41/a c d and the lattice parameters a = 28.235(3) and c = 39.950(4) A (Z = 64). In the crystal structure, polycations Bi95+ with the shape of tri-capped trigonal prisms are embedded in a chloro-bismuthate(III) framework ?3[Bi5Cl205-].

New Ru(III), Rh(III), and Pd(II) complexes with the ambident ligand 2-(3-pyridylmethyliminomethyl)phenol have been synthesized and characterized by electronic absorption and IR spectroscopy, 1H NMR, and elemental analysis and electrophoresis methods. The synthesis conditions and the nature of the metal turn out to have an effect on the coordination mode of the ligand in the resulting complexes. The existence of the intramolecular hydrogen bond in the ligand molecule is favorable for its coordination in the molecular form to the complex-forming metal. Nauka/Interperiodica 2007.

GdIII-containing metallostar contrast agents are gaining increased attention, because their architecture allows for a slower tumbling rate, which, in turn, results in larger relaxivities. So far, these metallostars find possible applications as blood pool contrast agents. In this work, the first example of a tissue-selective metallostar contrast agent is described. This RGD-peptide decorated RuII(GdIII) 3metallostar is synthesized as an alphavbeta 3-integrin specific contrast agent, with possible applications in the detection of atherosclerotic plaques and tumor angiogenesis. The contrast agent showed a relaxivity of 9.65 s-1 mM-1, which represents an increase of 170%, compared to a low-molecular-weight analogue, because of a decreased tumbling rate (tauR = 470 ps). The presence of the MLCT band (absorption 375-500 nm, emission 525-850 nm) of the central Ru II(Ph-Phen)3-based complex grants the metallostar attractive luminescent properties. The 3MLCT emission is characterized by a quantum yield of 4.69% and a lifetime of 804 ns, which makes it an interesting candidate for time-gated luminescence imaging. The potential application as a selective MRI contrast agent for alphavbeta 3-integrin expressing tissues is shown by an in vitro relaxometric analysis, as well as an in vitroT1-weighted MR image.

The synthesis and characterization of trans-aquatrichlorobis(5,7-dimethyl[1,2,4]triazolo[1,5-a]pyrimidine-N 3)ruthenium(III) monohydrate (1) are described. Complex 1 has been analysed spectroscopically and the crystal structure has been obtained by X-ray diffraction analysis, with an Rw value of 0.032. Crystals of 1, trans-[RuCl3(H2O)(dmtp)2] ·H2O, are monoclinic and belong to the space group C2/m with a = 14.160(3), b = 17.115(3) and c = 8.550(2) A, beta = 98.51(2) and Z = 4. The three chloride ions coordinate on the ruthenium(III) ion in a mer configuration, while the two dmtp molecules coordinate in a trans configuration. The coordinated water molecule stabilizes the parallel ‘face-to-face’ trans orientation of the dmtp ligands by hydrogen bonds of both its protons with the two N(3) nitrogens of the pyrimidine rings. Compound 1 is interesting for its structural similarity to the first hydrolysis product of ruthenium (III) complexes that are currently under investigation for applications in antitumour chemotherapy. Substitution reactions in coordinating solvents like acetonitrile and dimethylsulfoxide were followed in time with conductometry, UV-Vis absorption and proton NMR spectroscopy, and show the formation of neutral trichloro complexes which are formed by substitution of the coordinated water molecule in 1 by a solvent molecule.
