The gas-phase (electron diffraction) and solid-state (X-ray) structures of W(NBut)2(NHBut)2 (1) have been determined. In the gas phase, 1 adopts both C1 and C2 conformations in a 69:31 ratio. The solid-state structure is disordered over two equal sites, both showing approximate C2 conformation as in the gas phase; the imido and amido centers are, however, clearly distinguished. Compound 1 has been used to synthesize novel heterobimetallic derivatives W(NBu t)4[Rh(COD)]2 (3) and W(NBut) 4[Pd(η3-C3H5)]2 (4) via the dilithiated intermediate Li2[W(NBut) 4](2). In both cases, the [W(NBut)4] moiety bridges the two organometallic fragments. Reaction of 1 with Me2Zn has produced [Me(tBuN)W(μ-NBut)2ZnMe(NH 2But)] (5). The structures of 3, 4, and 5 have been determined. Thermal decomposition of 4 under an autogenerated pressure at 700 °C has formed the hitherto uncharacterized bimetallic alloy WPd2. © 2009 American Chemical Society.
