| Abstract: Complexes of[CuL2Cl]Cl·H2O (1),[NiL2(H2O)2](NO3)2 (2),[CuL2(H2O)2](ClO4)2 (3) and[CdL2(NO3)2]·CH3CN (4) were synthesized by the reactions of 4-methyl-3-phenyl-5-(2-pyridyl)-1,2,4-triazole (L) with CuCl2·2H2O, Ni(NO3)2·6H2O, Cu(ClO4)2·6H2O and Cd(NO3)2·4H2O, respectively. Their structures were determined by single crystal X-ray diffraction, and characterized by IR, UV-Vis, fluorescence and TGA. Complex 1 belongs to orthorhombic system with space group Fddd, and the central Cu1(Ⅱ) ion has a distorted tetragonal pyramid geometry[CuN4Cl]. The complexes of 2, 3 and 4 all belong to monoclinic system with space groups P21/n, P21/n and P21/c, respectively. All the central metal ions of 2, 3 and 4 have distorted octahedral configuration[NiN4O2],[CuN4O2],[CdN4O2]. | |
