| 摘 要： | A new Gd coordination polymer based on 2-（pyridin-4-yl）-I H-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） A,β= 106.176（6）°, Z = 4, V= 5262（3） A3, C40 H45 Gd3 N12 O30, Dc = 2.071 g/cm3, Mr=1645.63, λ （MoKa）=0.71073A, μ=3.846mm-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.

| Abstract: | 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) = 0.71073Å, 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. |
