The mononuclear and binuclear square-planar complexes of palladium(II) and platinum(II) cis-PtCl2(CO)2 (1), trans- Pt2Cl4(CO)2 (2), cis-PtBr2(CO)2 (3), and cis-Pd2Cl4(CO)2 (4), have been prepared by new synthetic procedures and some of them (2, 3, and 4) structurally characterised by X-ray diffraction methods. In the mononuclear platinum derivatives, cis-PtX2(CO)2, X=Cl, Br, the molecules are arranged
钯(II)和铂(II)的顺式-PtCl 2(CO)2(1),反式-Pt 2 Cl 4(CO)2(2),顺式-PtBr 2(CO )2(3),和顺式-Pd 2氯4(CO)2(4),制备了由新的合成方法,其中一些(的2,3和4)通过X射线衍射法进行结构表征。在单核铂衍生物cis -PtX 2(CO)2,X = Cl,Br中,分子排列在列中,Pt ⋯ Pt的间距为3.378Å(X = Cl)或3.65Å(av。,X = Br)。氯化物桥连的双核氯-羰基配合物M 2 Cl 4(CO)2,M = Pd,Pt,含有末端氯和羰基,对于铂衍生物2是反式的,但是对于相应的钯化合物4却是顺式的。包装基于分子间C ⋯ X或Pt ⋯Pt相互作用取决于卤化物的性质。铂(II)的四卤代配合物在存在作为卤化物清除剂的AlX 3的情况下在大气压和室温下羰基化会生成[PtX 3(CO)] -或PtX 2(CO)2,具体取决于Pt
