Abstract: The title compound, C₂₂H₂₀N₂O₄·2CHCl₃, a new Schiff base compound, lies across a crystallographic inversion centre. An intramolecular O-HN hydrogen bond generates a six-membered ring, producing an S(6) ring motif. Intermolecular bifurcated C-HO hydrogen bonds involving the two O atoms of the Schiff base ligand and the H atom of the chloroform solvent of crystallization, generate an R²₁(5) ring motif. The crystal structure is stabilized by intermolecular C-H and - interactions [centroid to centroid distance = 3.6158 (10) Å]. In the crystal structure, molecules are stacked down the c axis.
