| Abstract: A novel coordination polymer [Cu(3-cpoa)(phen)(H2O)]n(3-cpoa2-=3-carboxylphenoxyacetate, phen=1,10-phenanthroline) was synthesized and characterized by elemental analysis, IR spectra and single crystal X-ray diffraction. Crystallographic facts are as follows: monoclinic crystal system, space group P21/n， a=0.688 96(14) nm， b=1.652 3(3) nm， c=1.651 1(3) nm， β=95.20(3)°, V=1.871 9(6) nm3, Z=4, Dc=1.618 g·cm-3， F(000)=932， μ=1.211 mm-1，R=0.048 2 and wR=0.062 2. The copper atom exhibits a distorted square pyramidal coordination geometry, involving two oxygen atoms of different 3-cpoa2- ligands, two nitrogen atoms of 1,10-phen ligand and one coordinated water molecule. The copper atoms are bridged by 3-cpoa2- ligand, forming a one-dimensional chain along c axis. The distance of adjacent Cu…Cu is 0.916 6(4) nm. A three-dimensional network structure is constructed by the intermolecular hydrogen bond and π-stacking interactions. CCDC: 219724. |
