1,1′-Bis(diphenylthiophosphoryl)ferrocene complexes of gold(I) and gold(III)

Linear and three-coordinate gold(I) complexes with the ferrocenyl derivative 1,1′-bis(diphenylthiophosphoryl)ferrocene (dptpf) of the type [(μ-dptpf)(AuX)2] (X=Cl, 1; C6F5), [(μ-dptpf)(AuPPh3)2](ClO4)2 or [Au(dptpf)(PPh3)]ClO4 have been obtained. Oxidation of 1 with chlorine gave the mixed gold(I)–gold(III) compound [Au(dptpf)][AuCl4]. The dinuclear gold(III) complexes [(μ-dptpf){Au(C6F5)3}2] or [(μ-dptpf){Au(C6F5)2Cl}2] were obtained from the corresponding gold precursors and dptpf. The crystal structures of [Au(dptpf)][AuCl4] and [(μ-dptpf){Au(C6F5)2Cl}2] have been determined by X-ray diffraction studies.
