| 摘要: 以2，4-二氯苯乙酸、4，4'-联吡啶分别和硫酸镁、氯化钙和硝酸镉反应，采用自然挥发法制备了3个配合物[Mg（DCBA）2（H2O）4]·3（4，4'-bipy）（1）、[Ca（DCBA）（H2O）4]·DCBA·H2O（2）和[Cd（DCBA）2（H2O）2]·2H2O（3）（DCBA=2，4-二氯苯乙酸，4，4'-bipy=4，4'-联吡啶），并对其进行了元素分析、红外光谱、热稳定性和X射线单晶衍射的表征，研究了配合物3的荧光性质。结果表明，配合物1、2和3均为零维结构，其中，配合物1中存在O-H…O、O-H…N、C-H…O、C-H…Cl和O-H…π氢键作用，而配合物2和3中存在O-H…O和C-H…Cl氢键作用，并以此分别形成了3D超分子结构。 | |

| Abstract: Three new coordination complexes[Mg(DCBA)2(H2O)4]·3(4,4'-bipy) (1),[Ca(DCBA)(H2O)4]·DCBA·H2O (2) and[Cd(DCBA)2(H2O)2]·2H2O (3) were synthesized by evaporation methods using 2,4-dichlorophenylacetic acid (DCBA), 4,4'-bipyridine (4,4'-bipy) to react with MgSO4, CaCl2 and Cd(NO3)2, respectively. The complexes were characterized by elemental analysis, FT-IR, thermogravimetrie analysis (TGA) and X-ray single-crystal structure analysis, and fluorescence properties of the complex 3 have been studied. As a result, complexes 1, 2 and 3 are zero-dimensional structure. Among others, there are O-H…O, O-H…N, C-H…O, C-H…Cl, C-H…π and O-H…O, C-H…Cl hydrogen bonds contributing 3D supramolecular structure of 3 and 2, 3, respectively. | |
