| Abstract: Anew 2D Zn(Ⅱ) metal-organic framework, [Zn2(dib)(1,3-BDC)2(H2O)] (1), has been synthesized by the hydrothermal reaction of 1,3-benzenedicarboxylate with ZnSO4·7H2Oin the presence of 1,4-di(1-imidazoly)benzene (dib=1,4-di(1-imidazoly)benzene, 1,3-H2BDC=1,3-benzenedicarboxylate). The crystal is of monoclinic system, space group P21/n, with a=0.80367(12) nm, b=1.3327(2) nm, c=2.3725(4) nm, β=97.394(3)°, V=2.5199(7) nm3, Z=4, F(000)=1392, R=0.0520 and wR=0.0994 (I>2σ(I)). The two central zinc(Ⅱ) ions in the complex locate in a different coordination geometry, one is a distorted tetrahedral and the other is a distorted square-pyramidal coordination geometry, respectively. The dib ligand acts as a bridging ligand, which links the 1D double-chain into 2D layer structure. The net is linked into three-dimensional supramolecular network by O-H…Ohydrogen bonds. CCDC: 895702. |
