本文报道三苯基膦铂乙烯配合物（PPh 3）2 PtC 2 H4的X射线晶体结构分析。晶体属单斜晶系，a = 16.46（3），B= 10.85（2），c= 17.85（3），β = 100.5（1）°，空间群为P21/a，Z= 4个分子/晶胞，乙烯C-C距离为1.434（13）雅阁，与其它过渡元素形成金属环丙烷的结果一致。 结构已被各向异性全矩阵最小二乘法，finalR-因子为0.043为4174观察到的反射。
The X-ray crystal structure analysis of the triphenyl–phosphine platinum ethylene complex (PPh3)2PtC2H4is reported. The crystals belong to the monoclinic systema= 16.46(3),b= 10.85(2),c= 17.85(3) Å, β = 100.5(1)°, space groupP21/a,Z= 4 molecules per cell.The ethylene C—C distance of 1.434(13) Å is in accord with that found when other transition elements form metallo-cyclopropanes. The structure has been refined by anisotropic full-matrix least-squares, the finalR-factor being 0.043 for 4174 observed reflections.
