| Abstract: A novel coordination polymer, [Cu(m-BDOA)(bipy)·H2O]n (m-BDOA2-=benzene-1,3-dioxyacetate), was synthesized and characterized by elemental analysis, IR spectra, X-ray single crystal structure analysis. Crystallographic data are as follows: orthorhombic, space group Pna21, a=1.606 9(3) nm, b=1.685 9(3) nm, c=0.699 7(1) nm, V=1.8955(7) nm3, Z=4, Dc=1.619 g·cm-3, μ=1.200 mm-1, F(000)=948，R=0.038 1, wR=0.038 6. The copper atom is five-coordinated involving two oxygen atoms of different m-BDOA2- ligand, two nitrogen atoms of 2,2′-bipy ligand and one coordinated water, there is a distorted square pyramidal environment. Two copper atoms are bridged by m-BDOA2- ligand, forming a one-dimensional chain along a axis. The adjacent distance of Cu…Cu atoms is 0.877 3nm. The crystal network was formed by the intermolecular hydrogen bond and π-packing interactions. |
