摘要: 在无水乙醇中合成出2,2′-联吡啶-N,N′-二氧化物与氯化钕形成的配合物单晶Nd(bipyO2)2Cl3·6H2O.通过元素分析、红外光谱、差热、热重分析等对该晶体进行了组成及性质鉴定.X射线结构分析表明、该配合物晶体属单斜晶系,空间群为C2/C.晶胞参数a=17.456Å,b=7.491Å,c=21.078Å,α=γ=90°,β=100.66°,V=2708.9Å3.Nd3+离子与两个bipyO2,四个H2O分子和一个Cl-离子形成配位数为九的配阳离子,其中Nd-O(bipyO2)平均键长为2.511A,Nd-O(H2O)平均键长为2.500Å,Nd-Cl键长为2.899Å。

Abstract: The single crystal of the complex of neodymium chloride with 2,2'-bipyridine-N,N'-dioxide (bipyO2) has been synthesized in alcohol and characterized by elemental analysis, IR spectra, DTA and TG. The structure of this complex is determined by X-ray single crystal diffraction analyses. The crystal of the complex Nd(bipyO2Cl3·6H2O is monoclinic, space group C-cwith cell parameters: α= 17.456, b = 7.419, c = 21.078Å, β=100.66°, V=2708.9Å3, Z = 4, Dc= 1.802g/cm3, D0= 1.798g/cm3. The coordination number of neodymium is nine. Each neodymium atom is coordinated by four oxygen atom from bipyO2, four oxygen atoms from water and one chloride ion. The average bond lengthes are 2.511 Å for Nd-O (bipyO2) bond, 2.500Å for Nd-O(H2O) bond and 2.899Å for Nd-Cl bond respectively.
