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 been synthesized under hydrothermal conditions. The compound crystallizes in triclinic system, space group Pī with a=7.062(4), b=10.840(7), c=13.099(8), α=98.102(7), β=101.524(7), γ=107.961(7)°, V=912.3(10)3 , 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.
