摘要：
Three new zinc(II) complexes of [Zn(6-mbipy)(eta(2)-NO3)(2)] (1), [Zn(6,6'-dmbipy)(eta(2)-NO3)(2)] (2) and [Zn(5,5'-dmbipy)(eta(2)-NO3)(H2O)(2)](NO3).H2O (3) were prepared from the reaction of 6-methyl-2,2'-bipyridine (6-mbipy), 6,6'-dimethyl-2,2'-bipyridine (6,6'-dmbipy) and 5,5'-dimethyl-2,2'-bipyridine (5,5'-dmbipy) with Zn(NO3)(2)center dot 4H(2)O in methanol, respectively. These three complexes were thoroughly characterized by elemental analysis, thermal gravimetric analysis, differential thermal analysis, infrared, UV-Vis, H-1 NMR and C-13{H-1} NMR spectroscopy, and their structures have all been determined by the single-crystal X-ray diffraction. The luminescence spectra of the title complexes show that the intensity of their emission bands is stronger than the bands for the free ligands.
