Hexaamminecobalt(III)-4-hydroxybenzenesulfonate-chloride-water (3/8/1/13)

The title compound, [Co(NH3)6]3(C6H5O4S)8Cl·13H2O, contains one and a half hexa­mminecobalt(III) cations, four 4-hydroxy­benzene­sulfonate anions, one half chloride anion and six and a half water mol­ecules in its asymmetric unit. One [Co(NH3)6]3+ cation lies on a centre of inversion. The [Co(NH3)6]3+ cations and 4-hydroxy­benzene­sulfonate anions are linked by N—H⋯O hydrogen bonds into `triple-stranded ribbons'. The chloride anion is disordered in sites between these ribbons.
