Abstract

Treatment of the gold(I) halide species AuLCl (where L = PMe₃, PEt₃, PPh₃, PPh₂(C₅H₄N-2) or SPPh₃) and (AuCl)2(P-P) (where P-P = 1,4-bis(diphenylphosphino)butane or 1,1′-bis(diphenylphosphino)ferrocene) with 4-sulfanylbenzoic acid (1 or 2 equivalents as required) in the presence of sodium methoxide provided the corresponding phosphine gold(I) thiolate complexes AuL(4-SC₆H₄CO₂H) and [Au(4-SC₆H₄CO₂H)]₂(P-P), respectively. Addition of two equivalents of the acid (in the presence of NaOMe) to [N(PPh₃)₂][AuCl₂] yielded the dithiolate species [(N(PPh)₃)₂][Au(4-SC₆ H₄CO₂H)₂]. A polyaurated product [(Ph₃PAu)₂(4-SC₆H₄ CO₂H)]BF₄ was obtained on treating the acid with the oxonium complex [(Ph₃PAu)₃O]BF₄. The species AuL(4-SC₆H₄CO₂H) (L = PEt₃, PPh₃ or PPh₂C₅H₄N-2)) have been investigated crystallographically and reveal diverse structures incorporating aurophilic contacts, Au···S interactions and hydrogen bonding.
