| 摘 要： | The reaction of zinc carbonate with o-phthalic acid and imidazole in an aqueous-alcohol solution led to the formation of colorless crystals of Znμ-phthimi2]∞. Single-crystal X-ray analysis has revealed that the complex crystallizes in a monoclinic system, space group Pn with a = 8.394(2), b = 9.976(3), c = 9.959(3)A, β = 104.409(4)°, V = 807.6(4)A3, Z = 2, C14H12N4O4Zn, Mr = 365.6(5), Dc = 1.504 g/cm3, μ = 1.544 mm-1, F000 = 372, the final R = 0.0466 and wR = 0.1171 for 1834 reflections with I>2σ(I). The complex displays a zigzag infinite chain structure in which each zinc(Ⅱ)center is coordinated by two oxygen atoms and two nitrogen atoms to generate a ZnN2O2 distorted tetrahedral geometry. The neighboring zinc atoms are bridged by the o-phthalate ligand. Each chain is linked by hydrogen bonds with its neighbors to form a three-dimensional coordination polymer.
