Abstract: In the title compound, {[Co(C₁₂H₁₀N₂)(H₂O)₂](C₆H₆NO₃S)₂·6H₂O}_n, a cobalt coordination polymer, the repeat unit comprises a cobalt complex cation, two 4-aminobenzenesulfonate anions and six uncoordinated water molecules. In the doubly charged cobalt cation, each Co atom lies on a center of symmetry and is six-coordinated in a distorted octahedral geometry formed by four O atoms of four coordinated water molecules, and two N atoms from two (E)-1,2-bis(4-pyridyl)ethylene (bpe) ligands. The bpe ligands bridge the Co atoms, forming a one-dimensional linear chain. Intermolecular O-HO, O-HN and N-HO hydrogen-bonding interactions stabilize this chain structure.
