Abstract: By reaction of cobalt(II) sulfate with 5-hydroxyisophthalic acid and 2,2'-bipyridine in a water-dimethylformamide solution, the title novel sulfate-anion-bridged inorganic-organic hybrid, [Co(C₁₀H₈N₂)(H₂O)₂SO₄]_n, has been synthesized. Structural characterization of the complex shows that it displays a polymeric linear structure, formed by sulfate bridges between six-coordinate Co^II ions that lie on twofold rotation axes. Hydrogen bonding between chains results in a two-dimensional framework stucture.
