以1,4-二硝基苯甲酸及邻菲咯啉为配位的镧系金属配位聚合物的合成、结构及性质研究

Syntheses,Crystal Structures and Properties of Lanthanide Coordination Polymers Based on 2,4-Dinitro-benzoic Acid and 1,10-Phenanthroline

以1,4-二硝基苯甲酸(HL)和1,10-邻菲咯啉(phen)为配体,通过水热法与镧系金属盐合成了7个一维链状配位聚合物,其分子式为[Ce2L6(phen)2]n(1)和[LnL3phen]n(Ln=Sm,2;Eu,3;Gd,4;Tb,5;Dy,6;Er,7)。由X-射线单晶衍射测定了化合物晶体结构,通过磁性以及荧光测试表征了部分化合物的磁性和荧光性质。

Seven one-dimensional chain lanthanide coordination polymers based on 2,4-dinitro-benzoic acid （HL）and 1,10-phenanthroline （phen） as ligands were successfully synthesized with rare earth metal salts by hydrothermal method,namely,[Ce2L6（phen）2] n （1） and [LnL3phen] n （Ln=Sm,2; Eu,3; Gd,4; Tb,5; Dy,6; Er,7）.The compounds have been structurally confirmed by single-crystal X-ray diffractions and characterized by magnetic and fluorescent properties.CCDC：883735,1; 946599,2; 883736,3; 883836,4; 883837,5; 883838,6; 946598,7.
