mer-(4-aminobenzenesulfonato-kappa N)triapua(1,10-phenanthroline-kappa N-2,N ')cobalt(II) chloride

Both coordination and hydrogen bonds contribute to networking in the supramolecular title compound, [Co(C6H6NO3S)(C12H8N2)(H2O)(3)]Cl, which contains a discrete [Co(C6H6NO3S)(C12H8N2)(H2O)(3)](+) complex cation, formed by one 4-aminobenzenesulfonate ligand, one 1,10-phenanthroline ligand and three coordinated water molecules, together with one uncoordinated chloride anion. These discrete cations and chloride anions are connected by hydrogen-bonding interactions into a two-dimensional supramolecular motif. Further hydrogen-bonding interactions consolidate the structural architecture and extend the two-dimensional supramolecular structure into a three-dimensional network.
