چکیده
The Schiff base mol-ecule of the title compound, C(15)H(14)N(2)O(4)·C(3)H(7)NO, 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 dimethyl-formamide solvate mol-ecule. One of the hydr-oxy groups forms an intra-molecular hydrogen bond to the N atom of the C=N double bond, whereas the other forms an inter-molecular hydrogen bond to the carbonyl group.
