Synthesis and Crystal Structures of Samarium and Dysprosium Complexes with 3-bromine-4-methyl Benzoic Acid and 1,10-phenanthroline

摘要/Abstract

摘要：

采用水热法合成了2个新的稀土钐、镝金属配合物[Sm（3-Br-4-MBA）3（phen）（H2O）]2（1）和[Dy（3-Br-4-MBA）3（phen）（H2O）]2（2）（其中，3-Br-4-MBA=3-溴-4-甲基苯甲酸，phen=1，10邻菲啰啉）.利用X射线单晶衍射对其结构进行了测定.配合物1和2均为双核结构，具有相同的构型.配合物中的2个中心金属离子周围4个3-溴-4-甲基苯甲酸，2个1，10邻菲啰啉与2个水分子参与配位.每个中心金属离子周围的6个氧原子与2个氮原子共同形成了一个8配位的扭曲四方反棱柱构型.

Abstract：

Two new rare earth metal complexes:[Sm(3-Br-4-MBA)3(phen)(H2O)]2(1) and [Dy(3-Br-4-MBA)3(phen)(H2O)]2(2) (3-Br-4-MBA=3-bromine-4-methyl benzoic acid,phen=1,10-phenanthroline) had been prepared by hydrothermal method.Their structures were determined by X-ray single crystal diffraction. 1 and 2 are binuclear complexes with the same coordination structure.The complex contains two 1,10-phenanthroline,four 3-bromine-4-methyl benzoate and two H2O ligands.Each rare earth central metal is coordinated by six oxygen atoms and two nitrogen atoms and the complex has a distorted square antiprism structure.
