Poly[[bis(μ2-4-aminobenzenesulfonato-κ2 N:O)diaquamanganese(II)] dihydrate]

Abstract

The title compound, {[Mn(NH2C6H4SO3)2(H2O)2]·2H2O} n , was prepared under mild hydrothermal conditions. The unique MnII ion is located on a crystallographic inversion center and is coordinated by two –NH2 and two –SO3 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 μ2-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.
