    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.
