catena-Poly[[diaqua­manganese(II)]-di-μ-pyridine-3-sulfonato-κ2N:O;κ2O:N]

In the title polymeric complex, [Mn(C5H4NO3S)2(H2O)2]n, the Mn atom is located on a centre of inversion and is coordinated by two O atoms and two N atoms derived from four different pyridine-3-sulfonate (pySO3) ligands, and two O atoms derived from two water mol­ecules in a distorted trans-N2O4 octa­hedral geometry. The metal atoms are bridged by the pySO3 ligands to form a one-dimensional chain. The chains are further connected into a three-dimensional architecture via hydrogen bonds.
