摘要：

The ruthenium (II) mixed-ligand complexes cis-[Ru(bpy)2(NCS)2] (I), [Ru(bpy)2(pn)]2+ (II) and [Ru(bpy)2(phen)]2+ (III) (bpy, 2,2'-bipyridine; pn, 1,2-diaminopropane; phen, 1,10-phenanthroline) were subjected to two (for I and II), and three (for III) stepwise, one-electron reductions, and one-electron oxidations (all fully reversible); the products were studied in situ by solution UV-vis-near IR spectroscopy. The first two reductions took place in all cases on separate bpy ligands, while the third reduction of III took place on phen. Bands of the reduced species in the near IR-vis region are observed and assigned to anion radical ligands. Novel features of the LMCT bands of the oxidized species are presented and discussed.
