Resumo

The mononuclear pentafluorophenyl platinum complex containing the chelated diphenylphosphinous acid/diphenylphosphinite system [Pt(C6F 5){(PPh2O)2H}(PPh2OH)] 1 has been prepared and characterised. 1 and the related alkynyl complex [Pt(CCBu t){(PPh2O)2H}(PPh2OH)] 2 form infinite one-dimensional chains in the solid state based on intermolecular O-H⋯O hydrogen bonding interactions. Deprotonation reactions of [PtL{(PPh2O)2H}(PPh2OH)] (L = C 6F5 1, CCBut 2, CCPh 3) with [Tl(acac)] yields tetranuclear Pt2Tl2 complexes [PtL{(PPh2O) 2H}(PPh2O)Tl]2 (L = C6F5 4, CCBut 5, CCPh 6). The structure of the tert-butylalkynyl derivative 5, established by X-ray diffraction, shows two anionic discrete units [Pt(CCBut){(PPh2O)2H}(PPh2O)] - joined by two Tl(i) centres via Tl-O and Pt-Tl bonds. Despite the existence of Pt-Tl interactions, they do not show luminescence. This journal is © The Royal Society of Chemistry.
