Abstract

Under hydrothermal conditions a new Cd(II) polymer [Cd(dic)]n 1 (H4dic = 5-(3′,4′-Dicarboxylphenoxy)-isophthalic acid) was synthesized. The compound crystallizes in the space group C2 and the Monoclinic system, with b = 8.0043(9), a = 18.523(2), c = 16.5238(19) Å, β = 118.742(2)°,α = 90°, γ = 90°, Z = 1, V = 2148.1(4) Å3, Mr = 2728.38, Dc = 2.109 Mg/m3, F(000) = 1332, μ = 2.059 mm−1, the final wR = 0.0801 and R = 0.0317 for 3598 with I > 2σ(I) observed reflections. A three-dimensional (3D) network of the compound presents extended by both btc4- anions for a chelating coordination mode in which the dic4- anions employ. From the topology point of view, the structure with (4.62)(4.65.84) topology net could be described as a (3,5)-connected 3D network. Elemental analyses, Infrared spectroscopy, powder X-ray diffraction properties of 1 are also investigated and thermogravimetric analysis.
