Abstract: The ionic title compound, [Co(H₂O)₆][Co(C₁₄H₁₀O₆S)₂(C₅H₅N)₂]·4H₂O, consists of octahedrally coordinated [Co(H₂O)₆]²⁺ and [Co(C₁₄H₁₀O₆S)₂(C₅H₅N)₂]^2- ions along with four solvent water molecules. Both ions lie on inversion sites. In the anion, two 5-benzoyl-2-methoxy-4-oxidobenzenesulfonate ligands chelate the Co atom; the pyridine ligands occupy trans positions. A three-dimensional network structure results from hydrogen bonding involving the aqua ligands, sulfonate groups and solvent water molecules.
