In the mononuclear title complex, [Cu(CH3COO)2(C7H10N2)2], the CuII ion, located on a crystallographic inversion centre, is six coordinated by two N atoms of two 4-(dimethylamino)pyridine (DMAP) ligands in apical positions and four O atoms from two symmetry-related opposite acetate anions, which are asymmetrically bonded in the equatorial plane. The complex and the crystal packing of the complex are stabilized by intra- and intermolecular C-H...O hydrogen bonds, giving R42(10) rings and generating a layer-like structure.
