摘要：
A novel binuclear zinc(II) complex [Zn-2(azpy)(3)(2Cl-azpy)(2)(H2O)(6)](ClO4)(4)(azpy)(4)(H2O)(10) (1) (azpy=4,4'-azopyridine, 2Cl-azpy = (2,6-dichloro)-4,4'-azopyridine) has been synthesized and characterized by single crystal X-ray diffraction, IR and excitation and emission spectra. The Complex I crystallizes in the triclinic space group P (1) over bar, with a=10.730(3), b=15.455(4), c=18.893(5)A, alpha=73.358(5), beta=87.999(6), gamma=71.865(6)degrees, V=2847.7(14) Angstrom(3), Z = 1. The azpy ligand links two zinc(II) ions forming a binuclear entity. Each zinc(II) ion lies in a distorted octahedron completed by three oxygen atoms from water molecules and three nitrogen atoms from 4-pyridyl donor groups. Luminescence studies of I in aqueous solution show strong blue photoluminescence as the result of fluorescence from an intraligand excited state.
