Benzenehexathiol as a template rim for a golden wheel: synthesis and structure of [{CSAu(PPh3)}6]

Abstract

The reaction of benzenehexathiol, C₆(SH)₆, with [Au(PPh₃)Cl] in the presence of triethylamine gave the hexanuclear gold(I) compound [{CSAu(PPh₃)}₆] whose structure has been determined; the hexagon of the central benzene carbon atoms is surrounded by a hexagon of sulfur atoms, followed by a hexagon of gold atoms and the wheel-like structure is completed by six peripheral phosphine ligands with interlocked aryl groups.
