Abstract: Four complexes [Cu2Cl4pz*2] (1), [Cu2Cl4(L2)2] (2), [CuCl(L2)2·H2O]Cl·H2O (3) and [Ag(L3)2]NO3 (4) (pz*=3,5-dimethyl-1H-pyrazole, L2=di(1H-pyrazol-1-yl)methane, L3=4-iodo-3,5-dimethyl-1H-pyrazole) were designed and synthesized in the organic solvent system. The spectrum and structural characters of the four complexes were analyzed by elemental analysis, IR spectrum, UV spectrum, X-ray powder and X-ray monocrystal diffraction technology. The structural analysis shows that all pyrazolidines are in bidentate coordination mode and the coordination numbers of metal in complexes 1, 3 and 4 are five, six and two, respectively. However, there are two coordination modes for copper in complex 2. Furthermore, The stabilities and charge distribution of the three copper complexes were calculated by quantum chemistry.
