The reaction of tris(1-benzyllmldazole-2-yl)phosphine, (Bzim)3P, 1, with Ph3AsAuCl In 1:1 stoichiometric ratio produced (Bzim) 3PAuCl, 2. The reaction of (Bzim)3PAuCl with NaAuCl 4 in 1:1 stoichiometry in dichloromethane gives an orange-yellow crystalline tetranuclear gold(I) cluster [{μ-N,N-(Bzim)3PAuCl} 2Au2][AuCl2][AuCl4], 3. Complex 4, [{μ-N,N-(Bzim)3PAuCl}2Au2][AuCl 2]2 is formed when the reaction stoichiometry of (Bzim)3PAuCl and AuCl4-is 2:1. The crystal structure of 3 shows the formation of a 12-membered macrocycle with Au ... Au distances of ～3.0 A. The structures of (Bzim)3PAuCl and 3 show Au ... H - C interactions ranging from 2.57 to 2.95 A. Complex 2 crystallizes in the monoclinic space group P21/n (Z=4), a=9.1927(5), b=13.528(2), c=22.995(2) A, and ss = 94.537(5)°. Complex 3 crystallizes in the monoclinic space group P21/c (Z=4), a = 13.785(4), b = 21.426(6), c = 25.203(8) A, and ss = 96.51(6)°.
