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(PMe3)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-C4H6)3]− was obtained by a similar route.
