catena‐Poly[[[triaqua­sulfato­cobalt(II)]‐μ‐4,4′‐bipyridine] ethane‐1,2‐diol solvate]

In the title compound, {Co(SO₄)(C₁₀H₈N₂)(H₂O)₃]·C₂H₆O₂}_n, each Co^II center is octa­hedrally coordinated by two N atoms from two bridging 4,4′‐bipyridine (bipy) ligands and four O atoms, one from a monodentate sulfate ligand and three from aqua ligands. The bipy ligands occupy special positions of site symmetry and bridge adjacent cobalt(II) centers to form one‐dimensional linear coordination chains. Adjacent chains are arranged in a cross‐like fashion around the mid‐point of the bipy ligands, resulting in a three‐dimensional supra­molecular array.
