HEXAAQUACOBALT(II) BIS(2-AMINOTOLUENE-4-SULFONATE)

The title compound, [Co(H2O)(6)](C7H8NO3S)(2), has a structure built o f segregated layers of hexaaquacobalt(II) cations and 2-aminotoluene-4 -sulfonate anions, The Co atom is in a fairly regular octahedral coord ination environment of water molecules [Co-O range 2.046 (3)-2.111 (3) Angstrom]. 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) Angstrom]. The Mn and Zn salts are isostructural. These features are similar to those of other divalent metal organosulfonate salts.
