H. Xu, J. Dou, D. Li and D. Wang

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.
