Co-ordination complexes of polyoxomolybdates with a hexanuclear core: synthesis and structural characterization of (NBun4)2[Mo6O18(NNMePh)]

Abstract

Reaction of [MoCl₄(NNMePh)] with (Buⁿ₄N)₂[Mo₂O₇] yields a co-ordination complex with the hexanuclear oxomolybdate core, (Buⁿ₄N)₂[Mo₆O₁₈(NNMePh)]; the reaction is general with appropriate precursors in providing a ready entry into the class of co-ordination compounds of the types [Mo₅O₁₈(ML)]^n– and [W₅O₁₈(ML)]^n–, with M = Mo or W and L = NNR₂, NR, or N.
