    Abstract

    Reactions of Na(tmeda)[N(iPr2PTe)2] with CuCl, AgI or AuCl (in the presence of PPh3) in THF produced the coinage metal ditelluroimidodiphosphinate complexes {Cu[N(iPr 2PTe)2]}3, (5), {Ag[N(iPr 2PTe)2]}6 (6) and Au(PPh3)[N( iPr2PTe)2] (7), respectively. Complexes 5, 6 and 7 were characterized in the solid state by X-ray crystallography. Complex 5 is trimeric and exhibits a highly distorted Cu3Te3 ring. In contrast, the Ag(i) complex 6 is a hexamer, and forms a twelve-membered Ag6Te6 ring. The replacement of the iPr groups on phosphorus by Ph results in an intriguing structural change to a tetramer with a boat-shaped Ag4Te4 ring in {Ag[N(Ph 2PTe)2}4·2THF (8). The gold(i) complex 7 is monomeric. Aerosol-assisted chemical vapour deposition (AACVD) of compounds 5, 6 and 7 yields CuTe, Ag7Te4, AuTe2 and Au films, respectively. The films were grown at temperatures of 300-500 °C and characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive analysis of X-rays (EDAX). © The Royal Society of Chemistry 2007.
