　　A new cadmium (Ⅱ) polymer based on imidazole derivative, formulated as [Cd(Hiba)2]n (1), (H2iba =4-(1-H-imidazol-2-yl) benzoic acid) has been synthesized under hydrothermal condition.The compound crystallizes in triclinic system, space group P-1 with a =7.062(4), b =10.840(7), c =13.099(8) (A), α =98.102(7), β =101.524(7), γ =107.961(7)°, V =912.3(10) (A)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 cornected into a 3D supramolecular edifice through hydrogen bonding.The polymer exhibited 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.
