| Abstract: A metal-organic coordination polymer [Co(PDC)(bix)(H2O)]n(H2PDC=2,4-pyridinedicarboxyic acid, bix =1,4-bis(imidazol-1-ylmethyl)-benzene) 1 has been hydrothermally synthesized and structurally characterized by elemental analyses, TG, IR, UV and single-crystal X-ray diffraction. The complex crystallizes in monoclinic, space group C2/c with a=2.525 5(4), b=1.318 98(19), c=1.441 5(2) nm, β=118.656(2)°, V=4.213 5(11) nm3, C21H19CoN5O5, Mr=480.34, Dc=1.514 g·cm-3, μ(Mo Kα)=0.857 9 mm-1, F(000)=1 976, Z=8, R=0.030 5 and wR=0.067 4. In the crystalstructure, the cobalt atom is six-coordinated with two carboxylate oxygen atoms from two different PDC ligands and two nitrogen atoms from two bix ligands, one nitrogen atom from PDC ligand and one coordinated water moleculore, showing a distorted octahedral geometry. Furthermore, it exhibits a 3D supramolecular network through hydrogen bonding interactions. CCDC: 878877. | |||||||||||||
