cis-[Ru(Hmcpq)2(NCS)2] (1; Hmcpq=4-carboxy-2-(2?-pyridyl)quinoline) was newly synthesized, and its spectral (absorption, luminescence) and electrochemical properties were compared with those of cis-[Ru(H2dcpq)2(NCS)2] (2; H2dcpq=4-carboxy-2-[2?-(4?-carboxypyridyl)]quinoline). Solar cells based on nanocrystalline TiO2 film sensitized with 1 showed efficient photosensitization over a large portion of the visible and near-IR spectral region. These solar cells generated a large short-circuit photocurrent (12 mA cm-2), produced an open-circuit voltage of 0.53 V, and exhibited a solar energy conversion efficiency of 4.6% under simulated AM 1.5 solar irradiation (100 mW cm-2). The effects of the number of carboxyl groups in 1 and 2 on the binding to nanocrystalline TiO2 and on the photovoltaic performance of the solar cells were investigated.

Two ruthenium(III) complexes bearing the thiazole ligand, namely, thiazolium (bisthiazole) tetrachlororuthenate (I, TzlCR) and thiazolium (thiazole, DMSO) tetrachlororuthenate (II, TzNAMI) were prepared and characterized. The crystal structures of both complexes were solved by X-ray diffraction methods and found to match closely those of the corresponding imidazole complexes. The behavior in aqueous solution of both TzlCR and TzNAMI was analyzed spectroscopically. The time-dependent spectrophotometric profiles resemble closely those of the related ICR and NAMI-A anticancer compounds, respectively. It is observed that replacement of imidazole with thiazole, a less basic ligand, produces a significant decrease of the ligand exchange rates in the case of the NAMI-like compound. The main electrochemical features of these ruthenium(III) thiazole complexes were determined and compared to those of ICR and NAMI-A. Moreover, some preliminary data were obtained on their biological properties. Notably, both complexes exhibit higher reactivity toward serum albumin than toward calf thymus DNA; cytotoxicity is negligible in line with expectations. A more extensive characterization of the pharmacological properties in vivo is presently in progress.

Reference of 10049-08-8, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 10049-08-8, Cl3Ru. A document type is Article, introducing its new discovery.

The series of cis-(Et2-dcbpy)2RuX2 (Et2-dcbpy = 2,2?-bipyridine-4,4?-diethoxydicarboxylic acid, X = Cl-, I-, NCS-, and CN-) sensitizer precursor complexes have been synthesized directly from the esterified ligand (Et2-dcbpy) rather than via the acid (H2-dcbpy) in order to obtain high yields. The RuII/RuIII oxidation process, which is utilized in photovoltaic cell reactions, has been studied in detail by voltammetric and spectroelectrochemical techniques. The [(Et2-dcbpy)2RuCl2]0/+ process represents an example of an ideal reversible one-electron oxidation process. The very high stability of the oxidized complex allowed [(Et2-dcbpy)2RuCl2]0/+ to be characterized by spectroscopic techniques. The ESR spectrum indicates deviation from axial symmetry, and electronic spectra show the disappearance of both MLCT bands and the appearance of one LMCT band as expected for a metalbased oxidation process. Oxidation processes for the other complexes are considerably more complicated. In the case of (Et2-dcbpy)2RuI2 an oxidatively induced ligand elimination process was observed to occur after formation of [(Et2-dcbpy)2RuI2]+ to yield [(Et2-dcbpy)2RuI(Solvent)]+ and [(Et2-dcbpy)2Ru(Solvent)2]2+ complexes in dimethylformamide and acetonitrile. The rate constants for these reactions were estimated from digital simulation of voltammetric data. When dichloromethane was used as the solvent, formation of the five-coordinate [(Et2-dcbpy)2RuI]+ complex was observed. The identity of these complexes formed after the initial one-electron oxidation process was confirmed by electrospray mass spectrometry. Oxidation of L2Ru(CN)2 is even more complicated than oxidation of L2RuI2. Both mono- and polynuclear ruthenium compounds are formed as a result of reactions that occur with the oxidized form of the ligand, cyanogen (CN)2, or its derivatives. Oxidation of L2Ru(NCS)2 leads to elimination of sulfur from the thiocyanate ligand and to formation of L2Ru(CN)2.

The binary systems Ru-Se and Ru-Te were investigated using X-ray, microscopic, and thermal analysis. The only compounds found were RuSe//2 and RuTe//2. RuSe//2 crystallized n the pyrite type, while RuTe//2 was found to exist in both the pyrite and marcasite modifications. The previously unknown structure of RuTe//2 was established as the marcasite type through powder X-ray diffraction. For the ternary system Ru-Se-Te the triangle Ru-RuSe//2-RuTe//2 was investigated as an isothermal section at 800 degree C. The solid solutions RuTe//2(Se) and RuSe//2(Te) crystallize in the pyrite type. Below 400 degree C no solubility of selenium in marcasite-type selenium was observed.

Two fluorescent ligands, 3,5-dimethyl-4-(6?-sulfonylammonium- 1?-azonaphthyl)pyrazole (dmpzn, 1) and 3,5-dimethyl-4-(4?-N, N?-dimethylaminoazophenyl)pyrazole (dmpza, 2) were obtained by condensation of ketoenolic derivatives with hydrazine. 1 and 2 formed the novel dinuclear complexes [(H2O)3ClRu(mu-L) 2RuCl(H2O)3] (3 or 4) and [(H 2O)(NO)Cl2Ru(mu-L)2RuCl2(NO) (H2O)] (6 or 7) (where L = 1 or 2, respectively) which were characterized by IR, NMR and elemental analysis. The nitrosyl complexes were prepared by bubbling purified nitric oxide through methanol solutions of the corresponding ruthenium(ii) chloroderivative or by reaction of the appropriate ligands with Ru(NO)Cl3. Complexes 3 and 4 were found to bind NO, resulting in an increase in fluorescence. Ligand 1 also formed the mononuclear nitrosyl complex [Ru(NO)(bpy)2(dmpzn)]Cl2 (8) which released NO in water at physiological pH and in the solid state as revealed by fluorescence and IR measurements, respectively.

New copper and ruthenium mononuclear complexes of the type [ML 2(H2O)X] [X = H2O for M = Cu(II) and X = Cl for M = Ru(III)] have been prepared from 1-p-diphenyl- methane-2-hydroxyimino-2-(4- chloroanilino)-1-ethanone (HL1) and 1-p-diphenylmethane-2- hydroxyimino-2-(4-toluidino)-1-etha- none (HL2). The complexes were characterized by elemental analyses, magnetic susceptibility, molar conductance, IR, thermal analysis, and cyclic voltammetry. Stoichiometric and spectral results of the metal complexes indicated that the metal:ligand ratios in the complexes were found to be 1:2 and the ligands behave as a bidentate ligand forming neutral metal chelates through the carbonyl and oxime oxygen. The electrochemical behavior of the ligands and their complexes were obtained by cyclic voltammetry. The interaction between these complexes with DNA has also been investigated by agarose gel electrophoresis. The copper(II) complexes (3 and 4) with H2O2 as a co-oxidant exhibited strongest cleaving activity. Moreover, catalytic activities of the complexes for the disproportionation of hydrogen peroxide were also investigated in the presence of imidazole.

We report the use of RuCl3 as an “alkali metal sponge”. This is a general and highly efficient method for generating protonated parent ions for a variety of compounds that usually do not show this ion in electrospray mass spectrometry. This technique is demonstrated to be highly useful in “cleaning up” spectra from multiply metallated ions, thereby substantially improving the signal-to-noise ratio.
