Abstract

Hat trick: Homoleptic butadienemetalates of 4d and 5d metals have for the first time been structurally characterized. The niobium-naphthalene species [Nb(η4-C10H8)2(PMe 3)2]- functions as a useful source of "naked" Nb- ions in its reaction with 1,3-butadiene to afford an unprecedented homoleptic niobium-butadiene complex [Nb(η4-C4H6)3]- (see structure). The tantalum analogue [Ta(η4-C4H 6)3]- was obtained by a similar route.
