Abstract: The asymmetric unit of the title compound, C24H24N4O8·2C3H7NO, contains half of the centrosymmetric molecule of dimethyl 2,5-bis[2-(2-hydroxybenzoyl)hydrazino]cyclohexa-1,4-diene-1,4-dicarboxylate and one dimethylformamide solvent molecule. There is a dihedral angle of 61.7 (1)° between the central and two outer rings. The crystal structure involves N-HO, O-HO and C-HO hydrogen bonds.
