Abstract: The title bis-Schiff base compound, C₂₆H₂₈N₂O₄·C₂H₆O·H₂O, crystallizes as an ethanol and water solvate. Strong intramolecular O-HN hydrogen bonds generate S(6) ring motifs. The water H atoms form bifurcated O-H(O,O) intermolecular hydrogen bonds with the O atoms of the hydroxyl and ethoxy groups with R₁²(5) ring motifs, which may, in part, influence the molecular configuration. The dihedral angles between the central benzene ring and the two outer benzene rings of the Schiff base molecule are 5.64 (8) and 44.78 (9)°. The crystal structure is further stabilized by intermolecular C-HO and - interactions [centroid-centroid distances = 3.6139 (11)-3.7993 (11) Å].
