Diaqua­Bis[4-(Dimethyl­Amino)Benzoato-Κo](Isonicotinamide-Κn1)Manganese(Ii)

Abstract

The title MnII 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⋯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.
