摘要：
The reaction of [Pt](C=CPh)(2) (1) {[Pt] = (bipy)Pt; bipy = 2,2'-bipyridyl) with [CuX](n) (2a, X = Cl; 2b, X = Br) produces the heterodinuclear platinum(II)-copper(I) complexes of structural type {[Pt](C=CPh)(2)}CuX (3a, X = Cl; 3b, X = Br) in high yields. The result of the X-ray structure analysis of 1 and 3b is reported. Complexes 1 and 3b crystallize in the monoclinic space group P2(1)/c with the following parameters: 1: a = 17.5714(1), b = 15.1585(1), c = 15.0105(1) Angstrom, beta = 90.933(1)degrees, V = 3997.61(4) Angstrom(3) and z = 8; 3b: a = 9.5151(1), b = 10.5178(2), c = 22.0030(3) Angstrom, beta = 102.120(1)degrees, V = 2151.93(6) Angstrom(3) and Z = 4. In 3b both PhC=C ligands are sigma-bonded to the platinum atom as well as eta(2)-coordinated to the copper(I) center. The Pt(C=CPh)(2)CuBr building block is distorted from planarity. The copper atom is by 0.784(4) Angstrom out of the Pt(C=CPh)(2) plane.
