Abstract: The Schiff base molecule of the title compound, C15H14N2O4·C3H7NO, adopts a trans configuration with respect to the C=N double bond; the Schiff base itself is nearly planar (r.m.s. deviation 0.20 Å). The amido N atom is a hydrogen-bond donor to the dimethylformamide solvate molecule. One of the hydroxy groups forms an intramolecular hydrogen bond to the N atom of the C=N double bond, whereas the other forms an intermolecular hydrogen bond to the carbonyl group.
