摘　　要：以水/乙醇/乙腈为溶剂,采用溶剂热法,合成了两个结构新颖的异质同晶稀土配合物Ln(5-Cl-SA)3(Phen)2(Ln=Nd(1)、Ho(2),5-Cl-SA=5-氯水杨酸,Phen=邻菲啰啉)。利用X-射线单晶衍射(SCXRD)、元素分析(EA)、红外光谱(FTIR)、热重分析(TG)、荧光分光光度法(FS)等对其结构和光学性质进行了分析与表征。结果表明,两种稀土配合物均为单斜晶系、P21/c空间群,其中钕配合物(1)为十配位的双帽四方反棱柱构型,由于镧系收缩效应的影响,钬配合物(2)为九配位的三帽三棱柱构型,且两种配合物均具有良好的荧光性质。The novel ternary complexes Ln（5-Cl-SA）3（Phen）2[Ln = Nd（1）,Ho（2）,5-Cl-SA = 5-chloro salicylic acid,Phen = 1,10-phenanthroline]of Lanthanide rare earth ions and 5-chloro salicylic acid with 1,10-phenanthroline organic ligands in water-ethanol-acetonitrile were synthesized by solvothermal method.The structures and properties of the ternary complexs were analyzed and characterized by single crystal X-ray diffraction（SCXRD）,elemental analysis（EA）,fourier transform infrared spectrum（FTIR）,thermal gravimetric analysis（TG）,fluorescence spectrum（FS）.The results show that the complexes are both monoclinic system and space group P21/c,the complex of tencoordinated light rare earth neodymium exhibits a double capped square antiprism configuration,while due to the contraction effects makes the heavy rare earth holmium complex coordination geometry into nine coordinated tricapped prism configuration.The two complexes have good fluorescence properties.
