摘要：

A new Gd coordination polymer based on 2-(pyridin-3-yl)-1H-imidazole-4,5-dicarboxylate, formulated as {[Gd2(HPyIDC)2(H2O)5]·(bpy)·(NO3)2·3H2O}n(1, bpy = 4,4’-bipyridine) has been synthesized under hydrothermal conditions. The compound crystallizes in triclinic, space group P1 with a = 11.451(2), b = 11.596(2), c = 15.7333(3) , β = 79.47(3)°, Z = 2, V = 1948.6(7) 3, C30H34Gd2N10O22, Dc = 2.047 g/cm3, Mr = 1201.17, λ(MoKa) = 0.71073 , μ = 3.477 mm-1, F(000) = 1176, the final R = 0.0554 and wR = 0.1181. Polymer 1 is a 2D network built up from 4-connected HPyIDC2- anion and 4-connected Gd ions. Dielectric constant of complex 1 was measured at different frequencies with temperature variation.
