Abstract

The monohapto neutral 2-(diphenylphosphino)aniline PNH2 complexes [Au(C6F5)2X(PNH2)] (X = C6F5(1), Cl(2)) have been obtained from [Au(C6F5)3(tht)] or Au(C6F5)2 and PNH2, and the cationic [Au(C6F5)2- (PNH2)]ClO4 (3) has been similarly prepared from [Au(C6F5)2(OEt2)2] ClO4 and PNH2 or from 2 and AgClO4. The neutral amido complex [Au(C6F5)2(PNH)] (4) can be obtained by treatment of the chloro complex 2 with Tl(acac). It reacts with [Ag(OClO3)(PPh3)] or [Au(OClO3)(PPh3)] to give the dinuclear species [Au(C6F5)2{PNH(MPPh3)}] ClO4 (M = Ag (5), Au (6)). The latter can also be obtained by reaction of equimolar amounts of 3 and [Au(acac)(PPh3)]; when the molar ratio of the same reagents is 1:2, the trinuclear cationic complex [Au(C6F5)2{PN(AuPPh3}] ClO4 (7) is obtained. The crystal structures of complexes 2-4 and 7 have been established by X-ray crystallography; the last-mentioned displays an unusual Au(I)-Au(III) interaction.
