Hydrothermal synthesis,crystal structure and optical properties of the Samarium-5-sulfosalicylic acid compound

采用水-溶剂热法合成出钐配合物Sm(SSA)(H2O)2·H2O,并通过元素分析、红外光谱、热重分析对其结构进行表征,利用紫外及荧光分光光度计研究配合物的光学性能,用X-射线单晶衍射仪测定配合物的晶体结构.结果表明,晶体属于单斜晶系,空间群为P2(1)/n;晶胞参数a=0.888 44(16)nm,b=0.892 54(16)nm,c=1.436 6(3)nm,α=90.00°,β=100.810(2)°,γ=90.00°,Z=4,V=1.119 0(3)nm3(CCDC No.:875 346).中心金属离子Sm与周围的8个氧原子形成了四方反棱柱体的几何构型.

A complex Sm（SSA）（H2O ）2 · H2O has been synthesized from hydrothermal reaction and char- acterized by single crystal X-ray diffraction analysis, studied by element analysis, infrared spectrum and thermogravimetric analysis. The optical properties of the compound is studied by using UV-spectram and fluorescent analysis. The result shows that the crystal structure belongs to Monoclinic,space group P2 （1）/n with a=0. 888 44（16）nm,b=0. 892 54（16）nm,c=1. 436 6（3）nm,α=90.00°,β= 100. 810.（2）°,γ= 90.00°,Z= 4, V = 1. 1190 （3） nma （CCDC No. ： 875346）. The samarium （ III ） ion is eight-coordinated by eight oxygen atoms formed a four party reverse prismoid geometric configuration.
