| 摘 要： | 以吡啶-2,5-二羧酸(2,5-pyridinedicarboxylic acid,H_2L_1)、噻吩-2,5-二羧酸(Thiophene 2,5-dicarboxylic acid,H_2L_2)为主要配体,4,4′-联吡啶(4,4′-bipy)、菲咯啉(phen)为辅助配体,采用溶剂热法成功合成了3个过渡金属配合物:[Co_2(L_1)_2(bipy)(H_2O)_6]·bipy·H_2O (1)、[Cu(L_2)_2(bipy)_2]n(2)、[Ni_2(L_2)(phen)_2(H_2O)_4](3),并利用X射线单晶衍射法、红外光谱(IR)、荧光光谱(FL)和热重分析(TG/DTG)等测试手段对其进行了表征。单晶结构分析表明:配合物1、配合物2为P1空间群,配合物3为P2/n空间群;配合物1和配合物3为零维双核小分子结构,配合物2为二维层状结构。

| Abstract: | Three transition metal coordination polymer materials were successfully synthesized by solvothermal method with the main ligand 2,5-pyridinedicarboxylic acid (H2L1) or thiophene 2,5-dicarboxylic acid (H2L2), and co-ligand 4,4''-bipyridyl (4,4''-bipy) or 1,10-phenanthroline (phen). The complexes were characterized by X-ray single crystal diffraction, infrared spectroscopy (IR), fluorescence spectroscopy (FL) and thermogravimetric analysis (TG/DTG). The analysis of single crystal structure shows that all complexes belong to monoclinic system. Complexes 1 and 2 crystalize in P1 space group, and complex 3 crystalizes in P2/n. Complex 1 and complex 3 are zero-dimensional dinuclear small molecules, and complex 2 has a two-dimensional network structure. |
