Diaqua­bis[4-(dimethyl­amino)benzoato-κO](isonicotinamide-κN (1))manganese(II)

The title Mn(II) complex, [Mn(C(9)H(10)NO(2))(2)(C(6)H(6)N(2)O)(H(2)O)(2)], contains two 4-(dimethylamino)benzoate (DMAB) anions, one isonicotinamide (INA) ligand and two coordinated water mol­ecules. One of the DMAB anions acts as a bidentate ligand, while the other is monodentate. The four O atoms in the equatorial plane around the Mn atom form a highly distorted square-planar arrangement, while the distorted octa­hedral coordination geometry is completed by the N atom of the INA ligand and the O atom of the second water mol­ecule in the axial positions. In the crystal structure, strong inter­molecular O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds link the mol­ecules into a two-dimensional network parallel to (010). Two weak C—H⋯π inter­actions are also found.
