摘要
The coordination polymer [Co(pbc)(2)(H(2)O)](n)(Hpbc = 3-Pyrid-4-ylbenzoic acid) was prepared by hydrothermal synthesis and characterized by single-crystal X-ray diffraction, FTIR spectra and element analysis. X-ray diffraction analysis reveals that the pbc(-) ligands act as diconnectors to link two Co(II) centers and adopt a two coordination mode: mu (2)-N, O and mu (2)-N, O, O to form infinite wavy cobalt-carboxylate chains along the bc plane. Furthermore, compound, [Co(pbc)(2)(H(2)O)](n), shows intense photoluminescence at room temperature.
