Abstract: In the title compound, [Cu(C₁₆H₁₄N₄O)₂](C₆H₂N₃O₇)₂·4C₃H₇NO, the Cu^II ion is located on a crystallographic inversion center and is coordinated in a distorted octahedral environment by four N atoms and two O atoms forming two long Cu-O bonds. One of the unique dimethylformamide solvent molecules is disordered over two sites with occupancies of 0.715 (6) and 0.285 (6). The crystal structure is stabilized by intermolecular N-HO hydrogen bonds.
