【Abstract】 Two complexes, [Cu(DMPM)2(Bz)] [Cu(DMPM)(Bz)3]·H2O(1) and [Cu(PMA)Cl2](2)(DMPM =4,5-dimethyl-2-(2-pyridyl)imidazole, PMA=ethyl [2-(2-pyridyl)imidazole-1-yl)]acetate, Bz=benzoate anion) were synthesized and characterized by ultraviolet spectrophotometry(UV-Vis), thermogravimetric analysis(TG), differential scanning calorimetry(DSC), electron spin resonance(ESR) and single crystal X-ray diffraction. Results show that the crystal structure of complex 1 belongs to triclinic system, space group P1, and complex 2 belongs to monoclinic system, space group P21/c. Complex 1 assembles into a 3D structure by the intermolecular hydrogen bonding interactions, whereas a 2D layer structure of complex 2 is assembled by hydrogen bonds. CCDC:1414243, 1; 1414242, 2.更多还原
