The reaction of 2-(diphenylphosphanyl)aniline (1) with (tetrahydro/hiophene)gold(I) chloride in the molar ratio 1:1 gives a stable molecular complex 2, in which the gold atom is bonded to the phosphorus atom. Reaction of two equivalents of ligand 1 with one equivalent of the salt [(tht)2Au]ClO4 results in the displacement of both thioether ligands, affording the ionic complex {[(2-NH2C6H4)PPh2]2Au}+ ClO4- (3a), in which the metal center is exclusively P-coordinated. Treatment of [(tht)2Au]ClO4 with ligand 1 (1:1) affords the mixed P/S-coordinated complex 4, the structure of which has been confirmed by single-crystal X-ray diffraction. The reaction of ligand 1 with [(Ph3P)Au]+ BF4- leads to a mixture of products which are components of an equilibrium between the unsymmetrical salt ([(2-NH2C6H4)PPh2]Au(PPh 3)}+ BFJ with the two symmetrical species 3b (the BFJ analogue of 3a) and [(Ph3P)2Au]+ BFJ. With {[(Ph3P)Au]3O}+ BFj as the aurating agent, the ligand 1 (molar ratio 1:1) is converted into a polynuclear complex 7, which is tentatively assigned a structure with intimate aggregation of six gold atoms.
