catena-Poly[[diaqua(1H-imidazo[4,5-f] [1,10]phenanthroline)cobalt(II)]-μ-sulfato]

The Co-II ion in the title complex, [Co(SO4)(C13H8N4)(H2O)(2)](n), has a slightly distorted octahedral coordination environment formed by two O atoms from two symmetry-related bridging sulfate ligands, two N atoms from a bis-chelating 1H-imidazo[4,5-f][1,10]phenanthroline (IPL) ligand and two O atoms from coordinated water molecules. The bridging sulfate ligands connect Co-II ions to form a one-dimensional chain along the b-axis direction. In the crystal structure, intermolecular O-H center dot center dot center dot O, O-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds link the chains into a three-dimensional network.
