An Odd-Electron Complex [Ru~k(NO~(III))(Q~n)(terpy)]~(2+) with Two Prototypical Non-Innocent Ligands

摘要

Coordination compounds of redox-active transition metals, M, are most suitable for investigating intramolecular electron-transfer phenomena because of the typically well-defined structural framework and the variability of metals and redox-active "non-innocent" ligands, L. Apart from the standard two-component case, M-L, there has been some attention given to symmetrical three-component alternatives, such as M-L-M, involving for example, bridged mixed-valent species, or L-M-L, including for example, metal-bridged chelate ligands of the quinone-type. Less information is available for cases such as L~1-M-L~2, which would involve two different and thus potentially reacting non-innocent ligands in the coordination sphere of a redox-active transition metal.
