【Abstract】 The crystal of the complex [Cu(C 2O 4)(C 12 H 8N 2)(H 2O)]·2H 2O has been synthesized. The structure of the single crystal was determined by X-ray diffraction. The crystal is monoclinic system, space group P2 1/n with a=0.8442(4)nm, b=0.9686(1)nm, c=1.7424(2)nm, β=103.85(2)°, Z=4, R=0.036, Rw=0.047. There are two intermolecular hydrogen bonds in the crystal of the complex. They can link one molecule with another. This not only increases the crystal structure stability but also promotes the electrons transfer between the molecules, which will effect the magnetism of the complex. UV-VIS-NIR and IR spectra and the temperature dependence of the magnetic susceptibility have been measured and discussed.更多还原
