摘要
Under hydrothermal conditions, 4-(4,5-dicarboxy-lH-imidazol-2-yl)pyridine 1-oxide (H3DCImPyO) reacted with ZnC12 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 P21/c with a = 9.488(2), b = 13.247(3), c = 12.959(4) A, β = 126.716(19)°, Z = 4, V= 1305.6(6)/k3, C10H11N3O8Zn, Dc = 1.865 g/cm3, Mr = 366.61, 2(MoKa) = 0.71073 A, μ= 1.930 mm1, 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.
