Our examination of the reaction chemistry of polyhydride complexes, MHX(PR3)3, (x > 3), has relied principally on pho-tochemical1 and oxidative2 methods in order to enhance the reactivity of these coordinatively saturated species. We have more recently been attempting to produce polyhydride species of the first row transition metals since these metals (a) often violate the 18-electron rule as synthesized and (b) exhibit more rapid reaction rates than their heavier analogues. This report suggests that such a goal is indeed realizable, incorporating vanadium in a bimetallic polyhydride aggregate.Reaction of a THF slurry of [ V2(#t-C1)3(THF)6] 2Zn2Cl63 with PMePh2 (2 equiv/mol of V), followed by addition of LiBH4 ( 2
