Hat trick : Homoleptic butadienemetalates of 4d and 5d metals have for the first time been structurally characterized. The niobium–naphthalene species [Nb(η 4 ‐C 10 H 8 ) 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(η 4 ‐C 4 H 6 ) 3 ] − (see structure). The tantalum analogue [Ta(η 4 ‐C 4 H 6 ) 3 ] − was obtained by a similar route.
