Ph2P(4-C6H4PO3Et2) (ligand L′) were used to prepare different complexes of platinum(II) (1, cis-PtCl2L2; 2, trans-PtCl2L2·H2O; 3A and 3B, cis- and trans-PtCl2L′2) and palladium(II) (4, [PdCl2L]2; 5, trans-PdCl2L2·H2O; 6, trans-PdCl2L′2·CH2Cl2). The single-crystal X-ray structure analyses of complexes 1, 2, 4–6 indicate that complexation involved only the phosphine end, whereas the strong polarization
使用两个具有式Ph 2 P(CH 2)3 PO 3 Et 2(配体L)和Ph 2 P(4-C 6 H 4 PO 3 Et 2)(配体L ')的二乙基膦化膦配体制备不同的配合物铂(II)(1,顺式-PtCl 2 L 2 ; 2,反式-PtCl 2 L 2 ·H 2 O; 3A和3B,顺式和反式-PtCl 2 L' 2)和钯(II)(4,[的PdCl 2 L] 2 ; 5,反式-PdCl 2大号2 ·H 2 O; 6,反式-PdCl 2 L' 2 ·CH 2氯2)。复合物的单晶X射线结构分析1,2,4 - 6表示只涉及膦端即络合,而PO键的强极化通过形成氢键与水分子高亮2和5,并用在二氯甲烷分子6,具有一个特别短C H = O氢键长度(C = O分离3.094(3)Å)。
