A new Gd coordination polymer based on 2-(pyridin-3-yl)-1H-imidazole-4,5-dicar-boxylate, 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) Å, β=79.47(3)°, Z=2, V=1948.6(7) Å³, C₃₀H₃₄Gd₂N₁₀O₂₂, D_c=2.047 g/cm³, M_r=1201.17, λ(MoKa)=0.71073 Å, 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 HPyIDC^2- anion and 4-connected Gd ions. Dielectric constant of complex 1 was measured at different frequencies with temperature variation.
