【摘要】无水YCl3 与(tBuMe2SiC5H4)K在THF溶液反应制得[(tBuMe2SiC5H4)2Y(h-Cl)]2。晶体通过MoKa射线衍射法测定, 共收集到独立反射点5416个, 其中I > 2.0s(I)的反射点5154个。解析结果表明, 该晶体属单斜晶系, P21/c空间群。晶胞参数a = 11.559(2), b = 14.132(3), c = 16.127(3) , = 91.39(3)o, V = 2633.5(9) 3, Z = 2, Dc = 1.218 g/cm3, Mr = 966.13, m = 24.11 cm-1, F (000) = 1016, 最终偏离因子R = 0.0775, Rw = 0.2107。晶体结构显示, 标题配合物是一个中心对称的双氯桥二聚体结构。更多还原

【Abstract】 The reaction of YCl3 with two equivalent tBuMe2SiC5H4K in THF affords complex [(tBuMe2SiC5H4)2- YCl]2 which crystallizes in monoclinic, space group P21/c with a = 11.559(2), b = 14.132(3), c = 16.127(3) ? = 91.39(3), V = 2633.5(9) 3, Z = 2, Dc = 1.218 g/cm3, Mr = 966.13, m = 24.11cm-1 and F(000) = 1016. The least-squares refinement based on 5165 observed reflections (I > 2.0s(I)) converged to the final R = 0.0775 and Rw = 0.2107. The crystallographic data show that the title complex is a dichloride-bridged centrosymmetric dimmer.更多还原
