Gold and Silver Complexes with the Ligands N‐[Bis(isopropoxy)thiophosphoryl]thiobenzamide and N‐[Bis(isopropoxy)thiophosphoryl]N′‐phenylthiourea

Gold and silver complexes with the N‐[bis(isopropoxy)thiophosphoryl]thiobenzamide (HL1) and N‐[bis(isopropoxy)thiophosphoryl]‐N′‐phenylthiourea (HL2) ligands are reported. The compounds [M(HL)(PPh3)]TfO, [Ag(HL)(TfO)] and [Ag(HL)(PPh3)2]TfO were obtained by the reaction of both ligands with the corresponding trifluoromethanesulfonate salts. The (acetylacetonato)gold and ‐silver materials [M(acac)(PPh3)] or [Au(acac)(C6F5)2] cause deprotonation of the ligands and afford [ML(PPh3)] or [AuL(C6F5)2], whereas the reaction of [Au(TfO)(PPh3)] with HL1 in a 2:1 molar ratio in KOH/MeOH affords [Au2(L1)(PPh3)2]TfO. The first homoleptic anionic metal compounds [AuIL2]− are also reported. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
