Poly[[bis(μ(2)-4-amino­benzene­sul­fon­ato-κ(2) N:O)diaqua­manganese(II)] dihydrate]

The title compound, {[Mn(NH(2)C(6)H(4)SO(3))(2)(H(2)O)(2)]·2H(2)O}(n), was prepared under mild hydro­thermal conditions. The unique Mn(II) ion is located on a crystallographic inversion center and is coordinated by two –NH(2) and two –SO(3) groups from four 4-amino­benzene­sulfonate ligands and by two water mol­ecules in the axial positions, forming a slightly distorted octa­hedral coordination environment. The 4-amino­benzene­sulfonate anions behave as μ(2)-bridging ligands to produce a two-dimensional structure. In the crystal structure, inter­molecular N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds link the layers into a three-dimensional network.
