In the structure of the complex salt formed from the reaction of manganese(II) acetate with (4-aminophenyl)arsonic acid (p-arsanilic acid), [Mn(H2O)6](C6H7AsNO3)2·4H2O, the centrosymmetric Mn(H2O)6coordination polyhedron has slightly distorted octahedral stereochemistry, with the two hydrogen (4-aminophenyl)arsonate anions and the four water molecules of solvation related by inversion. Extensive O—H...O, O—H...N and N—H...O hydrogen bonds link all species, giving an overall three-dimensional
