| 摘 要： | Under hydrothermal conditions, 4-(4,5-dicarboxy-1H-imidazol-2-yl)pyridine 1-oxide (H3DCImPyO) reacted with ZnCl2 to give the 1D chain complex {Zn(DCImPyO)·(H2O)2·]·H3O}n (1). Single-crystal X-ray determination shows that complex 1 crystallizes in the monoclinic system, space group P2 1 /c with a=9.488(2), b=13.247(3), c=12.959(4) , β=126.716(19)°, Z=4, V=1305.6(6) 3 , C10H11N3O8Zn, D c=1.865 g/cm3 , M r=366.61, λ(MoKa)=0.71073 , μ=1.930 mm -1 , F(000)=744, R=0.0472 and wR=0.1487. Fluorescent analysis showed an intense emission band at 422 nm when the exciting radiation was set at 378 nm. Dielectric constant of complex 1 was measured at different frequencies with temperature variation.
