Özet

The title manganese complex, [Mn(C9H10NO2)(2)(C6H6N2O)(2)(H2O)(2)]center dot 2H(2)O, is monomeric and centrosymmetric. It contains two 4-(dimethylamino) benzoate ( DMAB) and two nicotinamide (NA) ligands, two coordinated and two uncoordinated water molecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Mn atom form a slightly distorted square-planar arrangement, while the distorted octahedral coordination is completed by the two NA N atoms in the axial positions. In the crystal structure, intermolecular O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonds link the molecules to form a supramolecular structure.
