Synthesis, Crystal Structure and Fluorescence Property of New Rare Earth Compound Nd(m-TA)_3

采用水热法,以间甲基苯甲酸(m-TA)为配体与硝酸钕配位构筑了一个稀土金属配合物Nd(m-TA)3。通过X-射线单晶衍射对稀土金属配合物的单晶结构进行了表征,利用元素分析、红外光谱、热失重分析和荧光分光光度计对配合物的晶形、元素百分含量、结构、热分解性质和荧光性进行了表征。结果表明该配合物晶体属单斜晶系,空间群为P2(1)/n,晶胞参数a=13.4427(11),b=7.5685(6),c=24.1915(16),α=90.00°,β=115.350(3)°,γ=90.00°,V=2224.3(3)3,Dc=1.641 g/cm3,Z=4,F(000)=1092。

The compound Nd（m-TA）3 was synthesized by the reaction of Nd（NO3）3.6H2O with m-toluic acid（m-TA）.The crystal structure of the compound was characterized by the method of single-crystal X-ray diffraction,EA,IR,TG-DTA and fluorescent emission spectra.The results showed that the compound crystallizes in a monoclinic system,space group P2（1）/n,cell parameter a = 13.4427（11）,b = 7.5685（6）,c = 24.1915（16）,α = 90.00,β = 115.350（3） °,γ = 90.00 °,V = 2224.3（3） 3,Dc= 1.641 g/cm^3,Z =4,F（000） = 1092.
