✦ Synopsis

The title complex, [Co(C 9 H 10 NO 2 ) 2 (C 6 H 6 N 2 O) 2 (H 2 O) 2 ]Á-2H 2 O, is monomeric with the Co atom situated on a crystallographic center of inversion. It contains two 4-(dimethylamino)benzoate (DMAB) and two nicotinamide (NA) ligands, and two coordinated and two uncoordinated water molecules, all ligands being monodentate. The four O atoms coordinating the Co 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. The crystal structure is determined by intra-and intermolecular O-HÁ Á ÁO and N-HÁ Á ÁO hydrogen bonds.
