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 CoII ions that lie on twofold rotation axes. Hydrogen bonding between chains results in a two-dimensional framework stucture.
