摘要： [Nd(DMSO)5(H2O)3]Cl3·H2O的单晶用ENRAF-NONIUS CAD 4型四圆衍射仪收集衍射数据进行结构分析,最终偏离因子R=0.036.晶体属三斜晶系空间群P1,晶胞参数a=9.800(1),b=10.531(1),c=14.757(2)Å;α=93.07(1),β=100.2l(1),γ=99.71(1)°;Z=2.结构分析证实:晶胞中有二个[Nd(DMSO)5(H2O)3]Cl3·H2O分子.Nd与五个DMSO及三个H2O中的氧形成八配位的畸变三角十二面体结构.Cl-与络阳离子通过离子键相互作用.[Tb(DMSO)5(H2O)3)Cl3·H2O的晶胞参数与之相近,有类似的结构.

Abstract: The crystal structure of [Nd(DMSO)5(H2O)3]Cl3·H2O was determined on an ENRAFNONIUS CAD4 diffractometer with X-ray intensity data collected in 0°<2θ<50°. The space group is P1 with a=9.800(1), b=10.153(1), c=14.757(2)Å; α=93.07(1), β=100.21(1),γ=99.71(1)°, Z=2. The structure was solved by Patterson method and refined with a fullmatrix least-squares procedure to R=0.036. Nd(Ⅲ) ions are coordinated by eight oxygen atoms forming a distorted dodecahedron. The crystal is stabilized through ionic bonds and hydrogen bonds as well.
