摘　　要：以3,5-二硝基水杨酸(H_2dns)和菲咯啉(phen)为配体合成了2个新的镧配合物[La_2(dns)_2(Hdns)_2(phen)_4](1)和[La_4(dns)_6(phen)_6](2),并对它们进行了红外分析、元素分析、热重分析和单晶结构分析。单晶衍射结果表明,配合物1和2均为三斜晶系,P1空间群。配合物1和2中La(Ⅲ)通过配体H_2dns桥联分别形成双核结构和四核结构。热重和荧光分析表明:2热稳定性高于1,1和2均在467 nm处有最强荧光发射强度。Two new complexes based on 3,5-dinitrosalicylic acid(H2dns)and 1,10-phenanthroline(phen),namely[La2(dns)2(Hdns)2(phen)4](1)and[La4(dns)6(phen)6](2)have been synthesized and characterized by IR,elemental analyses,thermogravimetric analyses and X-ray diffraction technique.Single-crystal X-ray diffraction analyses revealed that two complexes all crystallize in the triclinic system and space group P1.For complexes 1,H2dns ligands adopt tridentate and didentate coordination modes to link La(Ⅲ)ions into dinuclear structure.However H2dns ligands adopt tridentate coordination mode to link La(Ⅲ)ions into tetranuclear structure.TG and fluorescence analysis show the thermal stability of 2 is higher than that of 1,and 1 and 2 have same maximum emission band of the fluorescence at 467 nm.CCDC:1856530,1;1856531,2.
