The title compound, [Co(H2O)6](C7H8NO3S) 2, has a structure built of segregated layers of hexaaquacobalt(II) cations and 2-aminotoluene-4-sulfonate anions. The Co atom is in a fairly regular octahedral coordination environment of water molecules [Co-O range 2.046(3)-2.111 (3) Å]. The anions are arranged with the sulfonate groups directed to opposite faces of the layer in an alternating fashion. The layers are held together by a series of O-H⋯O hydrogen bonds between the water molecules and sulfonate O atoms [H⋯O range 1.89 (4)-2-10 (4) Å]. The Mn and Zn salts are isostructural. These features are similar to those of other divalent metal organosulfonate salts.
