Abstract

The first examples of bi- and polynuclear tellurocarbonyl complexes were obtained from the reactions of [W(≡CTe)(CO)₂(Tp*)]NEt₄ (Tp*=hydrotris(dimethylpyrazolyl)borate) with [MCl(PCy₃)]/TlPF₆ (M=Cu, Au) or [Au₂Cl₂(μ-dppm)], which afford [WM(μ-CTe)(PCy₃)(CO)₂(Tp*)] (M=Cu, Au) and [WAu₂(μ-CTe)(μ-dppm)(CO)₂(Tp*)]₃(PF₆)₃. In all cases it is specifically the tellurocarbonyl that assumes a bridging, but in each case distinct, role including examples of isotellurocarbonyl, semi-bridging and σ–π coordination and combinations thereof. Tetrametallic complexes bridged by C₂Te and C₂Te₂ ligands are also described.
