利用2-苯基-4-喹啉酸、苯-1,4-双(咪唑基-1-甲基)和乙酸钴在二甲基甲酰胺和水的混合溶剂中反应,得到配合物[Co(pqba)2(biyb)](1)(Hpqba=2-苯基-4-喹啉酸,biyb=苯-1,4-双(咪唑基-1-甲基))。采用元素分析、红外光谱、X单晶衍射结构分析、热重分析等方法对配合物进行了表征和结构测定。配合物1属单斜晶系,C2/c空间群。配合物1中的biyb配体采用双齿桥链模式连接金属钴离子首先形成一维“之”字链,通过π…π堆积作用,进一步拓展为二维超分子结构。循环伏安法测试结果说明配合物1的电解过程为准可逆过程。磁化率测量表明,配合物1具有反铁磁性质。
The reaction was carried out using 2-phenyl-4-quinolinic acid, benzene-1,4-bis (imidazolyl-1-methyl) and cobalt acetate in a mixed solvent of dimethylformamide and water to obtain a complex [Co (pqba) 2 (biyb)] (1) (Hpqba = 2-phenyl-4-quinolinic acid, biyb = benzene-1,4-bis (imidazolyl-1-methyl)). The complex was characterized and determined by elemental analysis, infrared spectroscopy, X-ray single crystal structure analysis and thermal gravimetric analysis. Complex 1 is a monoclinic, C2 / c space group. The biyb ligand in the complex 1 is connected to the metal cobalt ions by a double-dentate bridging mode and forms a one-dimensional “ ” chain first, which further expands into a two-dimensional supramolecular structure through π ... stacking effect. Cyclic voltammetry test results show that the complex 1 of the electrolysis process is quasi-reversible process. Magnetic susceptibility measurements show that complex 1 has antiferromagnetic properties.
