Abstract: 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-HO, O-HN and N-HO hydrogen bonds link the molecules into a two-dimensional network parallel to (010). Two weak C-H interactions are also found.
