配合物0.5222La（suc）（ox）（H O）2H O的合成、晶体结构及热分析研究

摘要

A new lanthanide complex 0.5 2 2 2[La(suc)(ox) (H O) ]2H O (1) (suc is succinic acid,ox is oxalic acid) has been synthesized under hydrothermal conditions and was characterized by X-ray diffraction single crystal structure analysis,elemental analysis and IR spectra. Complex 1 crystallizes in orthorhombic Fddd space group, with a=0.975 7(2)nm,b=1.556 8(3)nm,c=2.832 1(6)nm,α=β=γ=90°,V=4.301 8(15)nm 3,Z=8.Crystal structure and thermogravimetric analysis of complex 1 were analysized in detail.%采用水热法合成了一种新型稀土配合物0.5222[La(suc)(ox)(H O)]2H O （1）（suc 为琥珀酸根离子；ox为草酸根离子），并对该配合物进行了X射线单晶结构分析、元素分析及红外光谱表征．结构分析表明，该配合物属于正交晶系，Fddd空间群，晶胞参数a=0.9757（2）nm，b=1.5568（3） nm，c=2.8321（6）nm，α=β=γ=90°，V=4.3018（15）nm 3，Z=8．对配合物的晶体结构、热稳定性做了详细的分析．
