摘要 通过自然挥发法,合成了2个配合物[Cu(DMPM)2(Bz)][Cu(DMPM)(Bz)3]·H2O(1)和[Cu(PMA)Cl2](2)(DMPM=4,5-二甲基-2-(2-吡啶基)咪唑,PMA=[2-(2-吡啶基)咪唑-1-基]乙酸乙酯,Bz=苯甲酸根),并对其荧光、热稳定性及电子自旋共振光谱进行了研究。结构分析结果表明化合物1属于三斜晶系,P1空间群;化合物2属于单斜晶系,P21/c空间群。化合物1通过氢键的作用形成了三维超分子框架,化合物2通过氢键作用形成了二维层状结构。 Two complexes, [Cu(DMPM)2(Bz)I[Cu(DMPM)(Bz)3]-H2O (1) and [Cu(PMA)C12] (2) (DMPM=4,5-dimethyl-2-(2-pyridyl)imidazole, PMA=ethyl [2-(2-pyridyl)imidazole-l-yl)]acetate, Bz=benzoate anion) were synth-esized and characterized by ultraviolet spectrophotometry (UV-Vis), thermogravimetric analysis (TG), differentialscanning calorimetry (I)SC), electron spin resonance (ESR) and single crystal X-ray diffraction. Results show thatthe crystal structure of complex 1 belongs to triclinic system, space group P1, and complex 2 belongs tomonoclinic system, space group P21/c. Complex 1 assembles into a 3D structure by the intermolecular hydrogenbonding interactions, whereas a 2D layer structure of complex 2 is assembled by hydrogen bonds. CCDC:1414243, 1; 1414242, 2.
