Abstract

A square-shaped tetranuclear ruthenium(II) complex, [Ru^II₄Cl₅(bpmpm)₂]³⁺ [1; bpmpm = 4,6-bis[[N,N-bis(2′-pyridylmethyl)amino]methyl]pyrimidine], exhibited four reversible and stepwise one-electron-oxidation processes: chemical oxidation of 1 formed three different mixed-valence states, in one of which the charge is partially delocalized on the two Ru centers, to be evidenced by observation of an intervalence charge-transfer absorption band, categorized into the Robin-Day class II.
