Abstract
A new 2D coordination polymer {[Co(IPA)(L)]·0.25H2O} n (L = 1,4-bis(5,6-dimethyl-benzimidazolyl)-2-butene, H2IPA = 5-hydroxyisophthalic acid) is hydrothermally synthesized and characterized by elemental analysis, IR, and single crystal X-ray diffraction. The structure analysis indicates that the compound belongs to the orthorhombic system, space group Pnma, a = 17.5256(2) Å, b = 15.2074(2) Å, c = 9.7633(1) Å and Z = 4. The complex possesses a 2D (4, 4) network structure and the adjacent layers are further assembled into a 3D supramolecular framework via intermolecular O-H⋯O hydrogen bond interactions. The luminescent properties of the compound and free ligand L are investigated in the solid state.
