摘要A new cadmium(II) polymer based on imidazole derivative, formulated as [Cd(Hiba)2]n1, H2iba = 4-(1-H-imidazol-2-yl) benzoic acid), has beensynthesized under hydro- thermal conditions. The compound crystallizes in triclinic system, space group Pīwith a = 7.062(4), b = 10.840(7), c = 13.099(8) Å, α = 98.102(7), β = 101.524(7), γ = 107.961(7)°, V = 912.3(10) Å3, Z = 2, Mr= 486.75, Dc=1.772 Mg/m3, μ = 1.234 mm-1, F(000) = 484, the final R = 0.0735 and wR = 0.1739 for 2154 observed reflections with I > 2σ(I). Polymer 1 consists of(Cd-Hiba)2 zigzag chains, which are further linked by hydrogen bonding to extend into a two-dimensional (2D) corrugated-shape sheet structure. The 2D structures are further connected into a 3D supramolecular edifice through hydrogen bonding. The polymer exhibits exceptional high thermal stability. The bulk purity of the materials of 1 was confirmed through the powder X-ray diffraction (PXRD) patterns. The luminescent property of polymer 1 has also been investigated.
