[Fe4Te4(SPri)4]2– and [Fe4Te4(SPri)4]3–, novel Fe4Te4 cluster complexes in different metal oxidation states and [Mn4Te4(TePri)4]4–, the first chalcogenide cubane cluster containing divalent metal ions
Abstract
A novel series of M4Te4 cubane cluster complexes with average metal oxidation states ranging from +2.5 to +2.25 for M = Fe and finally reaching +2 on replacing Fe by Mn is described; the corresponding [Mn4Te4(TePri)4]4– anion represents the first member of the mixed manganese/chalcogenide/chalcogenolate class of complexes.
