摘要：

AgCl reacts with Ph2PSiMe3 in the presence of a tertiary Phosphine PMe3 or PtBu3 to form the multinuclear complexes [Ag4(PPh2)4(PMe3)4] (1) and [Ag6(PPh2)6(PtBu3)2] (2). In analogy to that MCl2 reacts with Ph2PSiMe3 in the presence of pn Pr, to form the two multinuclear complexes [M4Cl4(PPh2)4(PnPr3)2] (M = Zn (3), Cd (4)). The structures were characterized by X-ray single crystal structure analysis (1: space group Pna2(1) (Nr. 33), Z = 4, a = 1313.8(11) pm, b = 1511.1(6) pm, c = 4 126.0(18) pm, 2: space group P1BAR (Nr. 2), Z = 2, a = 1559.0(4) pm, b = 1885.9(7) pm, c = 2112.4(8) pm, alpha = 104.93(3)-degrees, beta = 94.48(3)-degrees, gamma = 104.41(3)-degrees; 3: space group C2/c (Nr. 15), Z = 4, a = 2 228.6(6) pm, b = 1847.6(6) pm, c = 1 827.3(6) pm, beta = 110.86(2); 4: space group C2/c (Nr. 15), Z = 4, a = 1894.2(9) pm, b = 1867.9(7) pm, c = 2 264.8(6) pm, beta = 111.77(3)-degrees). 3 and 4 may be considered as intermediates on the route towards polymeric [M(PPh2)2]n (M = Zn, Cd).
