Redox interconversions and aqueous solution properties of the cuboidal complexes [Mo4S4(edta)2]m- (m = 4, 3, 2)

Abstract

Redox interconversions of the recently prepared Mo 4 S 4 complexes present in the 4+, 5+, and 6+ states, and in this case with N,N,N',N'-ethylenediaminetetraacetate (edta) as ligand, have been studied at 25°C. The most readily obtained complex in green [Mo 4 S 4 (edta) 2 ] 3- , the EPR spectrum of which (in H 2 O at 10 K) confirms one unpaired electron
