Tetracarbonyltungsten(0)-bis(μ-dimethylphosphido)-bis[dicyclopentadienylhydridomolybdenum(IV)]

The title trinuclear WMo2 compound, [Mo2WH2(C5H5)4(C2H6P)2(CO)4], was obtained by opening of the hydride bridge in the dinuclear dibridged (μ-PMe2,H){(C5H5)2Mo}{W(CO)4} complex (MoIV) upon the action of (C5H5)2Mo(PMe2H) (MoII) in THF solution. This involves the formal conversion of MoII to MoIV.
