The title Mn-II complex, [Mn(C9H10NO2) (2)(C6H6N2O)(H2O)(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 center dot center dot center dot O, O-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds link the molecules into a two-dimensional network parallel to (010). Two weak C-H center dot center dot center dot pi interactions are also found.
