| 摘要: 用NdCl3,NaS2CNEt2和Et4NBr为原料,在甲醇溶剂中反应,生成钕配合物,[Et4N](Nd(S2CNEt2)4]晶体,用X-射线衍射法测定了配合物的晶体结构。晶体属于单斜晶系,空间群P21/n晶胞参数,a=11.704(3)Å,b=20.941(3)Å,c=17.564(4)Å,V=4242.2Å3,Z=4。结构经最小二乘方法修正后偏离因子为R=0.0564.在配合物钕离子是通过8个硫原子配位形成扭曲的NdS8核的十二面体。井对配合物的红外线光谱和紫外可见光谱也进行了研究。 |

| Abstract: The crystal of Neodymium coordination compound,[Et4N][Nd(S2CNEt2)4]was obtained by the reaction of NdCI3,NaS2CNEt2and Et4Br in MeOH,and the crystal structure was obtained by X-ray diffraction.The crystal belongs to space group P21/n ofmonoclinic system.The crystal cell parameters are a=11.704(3)Å,b=20.941(3)Å,c=17.564(4)Å,V=4242.2Å3 and Z=4.The block least-square refinement for all structure parameters gives final discrepancy factor R=0.0564.In coordination compound,the neodymium ion is coordinated by eight sulphur atoms adopting a distorted dodecahedral geometry of NdS8 core.The crystal has been further studied by using IR and UV-visible. |
