In the title compound, [Mn(C(8)H(8)N(3)O(3)S(2))(2)(H(2)O)(4)], the Mn(II) atom (site symmetry ) adopts a slightly distorted octa-hedral MnO(6) geometry. The mol-ecular conformation is supported by N-H⋯N and O-H⋯O hydrogen bonds. In the crystal, mol-ecules inter-act by O-H⋯O, O-H⋯S, N-H⋯O and N-H⋯S hydrogen bonds, thereby forming (011) sheets.
