Abstract

Abstract Reaction of Li2[W(NBut)4] with two equivalents of SbCl3 at −78 °C yields orange-red crystals of the novel heterobimetallic Sb2W(NBut)(μ2-NBut)(μ3-NBut)2Cl3(μ2-Cl) (1) in low yield (25%). From a 1:4 reaction stoichiometry, in addition to 1 crystals of [ W(NBu 2 t )(H2NBut)Cl2]2. trans-[Sb(Cl)(μ-NBut)]2 (2), [ W(NBu 2 t )(H2NBut)Cl2]2.SbCl3 (4), Sb2W3Cl7(μ2-O)(μ3-O)2( NBu 2 t )3(NHBut)(μ2-NBut)2 (3) and Sb2W(NBut)(μ2-NBut)(μ3-NBut)2Cl3(μ2-Cl). Sb2W3Cl7(μ2-O)(μ3-O)2(NBut)3(NHBut)(μ2-NBut)2 (5) have been characterised.
