A novel coordination polymer constructed with [Co(3,3'-bpbc)(H2O)3]×H2O(I) (3,3'-bpbc = 2,2'-bipyridine-3,3'-dicarboxylic acid) is successfully synthesized at room temperature and characterized by elemental analysis and IR spectra. The crystal structure of the complex is determined by single crystal X-ray diffraction. The unit cell parameters for complex I are: a = 9.9606(11) Å, b = 9.2552(10) Å, c = 16.0258(17) Å, β = 96.731(0)°, V = 1467.2(3) Å3, Z = 4, space group P2(1)/n. In the crystal, the cobalt(II) ion adopts a hexa-coordinate environment, and the structure units aggregate together to give birth to infinite 1D chains. The 2D and 3D framework is constructed via intermolecular hydrogen bonds.
