The crystal structures of M2[PtCl2(SnCl3)2][M = PMePh3(1) and PPh3(CH2Ph)(2)] have been determined from three-dimensional X-ray data collected by counter methods. Compound (1) crystallises in space group P21/n with a= 11.815(2), b= 14.172(3), c= 13.848(2)Å, β= 96.56(1)°, and Z= 2. Compound (2) crystallises in space group P, with a= 12.722(3), b= 11.518(2), c= 10.674(2)Å, α= 110.73(1), β= 79.86(2), γ=
M 2 [PtCl 2(SnCl 3)2 ] [M = PMePh 3(1)和PPh 3(CH 2 Ph)(2)]的晶体结构已通过反方法收集的三维X射线数据确定。化合物(1)在空间群P 2 1 / n中以a = 11.815(2),b = 14.172(3),c = 13.848(2)Å,β= 96.56(1)°和Z = 2结晶。 (2)在空间群P中结晶,a = 12.722(3),b = 11.518(2),c= 10.674(2)Å,α= 110.73(1),β= 79.86(2),γ= 114.39(1)°,Z =1。两种结构均采用最小二乘法精炼:精炼在R =处停止(1)为0.13;对于(2)的改进在结束- [R = 0.033 3个344反射与我/σ(我)3.0。两种晶体均含有顺式-[PtCl 2(SnCl 3)2 ] 2-离子,以伪中心对称的方式无序排列。这种无序涉及在中心的任一侧出现一半的PtCl
