The cyclic voltammetric properties of a series of double-pseudo-cubane cluster compounds (Et4N)4[Mo2Fe7S8(SR)12](R=Ph,1;R=o-tolyl,2;R=m-tolyl,3;R=P-tolyl,4)were studied in 0--2.0V vs.SCE.All the compounds showed two redox couples corresponding to the single-electron rcdox reaction of two [MoFe3S4]3+ cubanc cores respectively.Möss-bauer spectrum of 3·2THF recorded at liquid nitrogen temperature indicates the existence of three types of Fe site in the compound.They are four coordinate 2Fe(Ⅲ)+Fe(Ⅱ)of high spin in the[MoFe3S4]3+ core with average oxidation state of Fe at+2.67 and six-coordinate Fe(Ⅱ) of high spin in Fe(SR)6 bridge.
