groups with O ⋯ O 2.41 Å. Similar complexes [M(S–S)(PPh2O)PPh2(OH)}](M = Pd, S–S–=[S2PPh2]– or [S2CNEt2]–; M = Pt, S–S–=[S2PMe2]– or [S2CNEt2]–) have been prepared by reaction of [M(S–S)2] with PPh2(OR) or, for M = Pd, by reaction of [PdCl(PPh2O)[PPh2(OH)]}2] with the appropriate dithioacid anion (1 : 2 molar ratio). A careful study of the [Pt(S2CNEt2)2]–PPh2(OMe) reaction has resulted in the isolation
[Pd(S 2 PMe 2)2 ]与过量的PPh 2(OR)(R = Me或Et)在二氯甲烷或苯中的长时间反应,得到四配位络合物[Pd(S 2 PMe 2)(光谱证据和X射线结构分析表明,PPh 2 O)PPh 2(OH)}](1a)含有对称氢键合的Ph 2 POHOPPh 2配体。(1a)的晶体是单斜晶体,空间群P 2 1 / m,a = 6.86(1),b = 22.12(2),c= 9.69(1),,β= 111.5(2)°。酸性氢原子用O di O 2.41Å连接两个等效的二苯基亚膦酸酯基团。相似的配合物[M(S–S)(PPh 2 O)PPh 2(OH)}] [M = Pd,S–S – = [S 2 PPh 2 ] –或[S 2 CNEt 2 ] – ; M = Pt,S–S – = [S 2 PMe 2 ] –或[S 2 CNEt 2 ] –)是通过[M(S–S)2 ]与PPh
