Trans-effects in octahedral transition metal complexes

Structure, chemical and photochemical reactivity and biological activity of some ruthenium amine nitrosyl complexes

Transition metal basicity

Spectrofluorimetry was used to measure the quenching of *Ru(pby)/sub 3//sup 2 +/ luminescence using the reducing agents Fe(CN)/sub 6//sup 4 -/, Co(phen)/sub 3//sup 2 +/, Ru(NH/sub 3/)/sub 6//sup 2 +/, Eu(II), S/sub 2/O/sub 4//sup 2 -/, Fe/sup 2 +/ and Mo(CN)/sub 8//sup 4 -/. Data, including the reduction potential, the electron self-exchange rate constant, the Stern-Volmer constant, quenching rate constant, and spectral data concerning the position(s) of the lowest energy excited states available to the reducing agent quenchers, was tabulated using experimental data and some literature data. The experimental results indicate the role of *Ru(bpy)/sub 3//sup 2 +/ as a strong oxidizing agent in the electron transfer process. (DDA)

Electron-transfer reactions of excited states. Reductive quenching of the tris(2,2'-bipyridine)ruthenium(II) luminescence

A new route was developed for preparing a series of trans nitrosyl complexes of general formula trans-[Ru(NH3)4L(NO)](BF4)3, where L = imidazole, l-histidine, pyridine, or nicotinamide. The complex...
