摘要:
The 1:1 reaction of [Au(acac)(PPh(3))] (Hacac = acetylacetone) with ammonium salts [HL]X (X = CF3SO3, L = 2-nitroaniline, 4-methoxyaniline. NHPh(2) or NHEt(2); X = ClO4, L = NMe(3)) in diethyl ether gave complexes [Au(PPh(3))L]X and acety]acetone. The crystal structure of [Au(PPh(3))(NMe(3))][ClO4] was determined; orthorhombic, space group P2(1)2(1)2(1), a = 9.498(2), b = 10.322(2) c = 26.154(4) Angstrom, wR(F-2) 0.091. The gold atom is linearly co-ordinated to both ligands [AU-P 2.231 (2). Au-N 2.108(7) Angstrom, P-Au-N 179.3(2)degrees] and no intermolecular Au..Au contacts exist.
