Dinuclear and Dendritic Polynuclear Ruthenium(II) and Osmium(II) Polypyridine Complexes: Electrochemistry at Very Positive Potentials in Liquid SO
The electrochemistry in liquid SO2 of RuII and OsII dendritic polynuclear complexes (two hexanuclear species, having as the core a bis-chelating ligand, and one decanuclear species, built around a metal core) has been performed together with that of several of their lower-nuclearity analogues (five dinuclear and one trinuclear species), which can be considered as components of the larger dendri...
متن کاملCharacteristics of Temperature Programmed Decomposition of Osmium Cluster Catalysts
Products of T.P.D. per cent CO CO, C,H,+C,H, Recent studies of catalysis by supported metal cluster compounds have shown that these systems exhibit novel behaviour. Although diffzcult to characterise, by using a combination of analytical techniques an overall picture can be developed of the cluster nuclearity and the number and type of ligands present. Chemisorption and catalytic studies have b...
متن کاملOsmium–Germanium and Osmium–Germanium–Gold Carbonyl Cluster Complexes: Syntheses, Structures, Bonding, and Reactivity
Reactions of Os3(CO)10(NCMe)2 with HGePh3 have yielded the compounds Os3(CO)10(NCMe)(GePh3)(μ-H) (1) and Os3(CO)10(GePh3)2(μ-H)2 (2) by the sequential replacement of the NCMe ligands and the oxidative addition of the GeH bonds of one and two HGePh3 molecules, respectively, to the osmium atoms of the cluster. Compound 2 exists as two isomers in solution at low temperatures which interconvert rap...
متن کاملIn‐Cell Activation of Organo‐Osmium(II) Anticancer Complexes
The family of iodido OsII arene phenylazopyridine complexes [Os(η6 -p-cym)(5-R1 -pyridylazo-4-R2 -phenyl))I]+ (where p-cym=para-cymene) exhibit potent sub-micromolar antiproliferative activity towards human cancer cells and are active in vivo. Their chemical behavior is distinct from that of cisplatin: they do not readily hydrolyze, nor bind to DNA bases. We report here a mechanism by which the...
متن کاملTHE ACTIVATION OF CARBON DIOXIDE AT A MAGNESIUM (1 00) SURFACE THE ROLE OF OXYGEN TRANSIENTS
X-ray photoelectron and high resolution electron energy loss spectroscopic (XPS-HREELS) studies have shown that the adsorption of carbon dioxide at Mg(100) surfaces at 80K is followed by a dissociative reaction leading to the formation of a metastable surface carbonate above 80K. The formation of a carbonate species is proposed to proceed through oxidation of C0 (g) by an active oxygen su...
