Transition-metal dithiolene complexes. Part XX. Dicyano-1,2-dithiolene complexes of rhenium

Abstract

A voltammetric study of the complex previously formulated as [Re{S2C2(CN)2}2]22– has shown that it must be reformulated as [Re{S2C2(CN)2}2]44–, which undergoes one one-electron reduction and two one-electron oxidation processes. Oxidation of [Re{S2C2(CN)2}3]2– with iodine afforded [ReO{S2C2(CN)2}2]–, which may be reduced voltammetrically to a dianion.
