A new Gd coordination polymer based on 2-(pyridin-4-yl)-1H-imidazole-4,5-dicarboxylate (H3PIDC) has been synthesized under hydrothermal conditions, formulated as {[Gd3(HPIDC)3(PIDC)(H2O)4]·3H2O}n (1). The compound crystallizes in the monoclinic system, space group C2/c with a = 20.951(7), b = 9.515(3), c = 27.483(10) Å, β = 106.176(6)°, Z = 4, V = 5262(3) Å3, C40H45Gd3N12O30, Dc = 2.071 g/cm3, Mr = 1645.63, λ (MoKa) = 0.71073 Å, μ = 3.846 mm−1, F(000) = 3204, the final R = 0.0390 and wR = 0.1332. Complex 1 is a two-dimensional MOF built up from T-shaped 3-connected HPIDC2−, PIDC3− and 4-connected metal nodes. Dielectric constant of complex 1 was measured at different frequencies with temperature variation.
