(2,4-Dimethoxy­benzyl­idene)-2-hydroxy­benzohydrazide ethanol solvate

摘要

In the planar title mol­ecule, C16H16N2O4·C2H6O, the planar Schiff base molecule is linked to the ethanol solvent mol­ecule by a hydr­oxy–amide hydrogen bond. The hydr­oxy group of the ethanol mol­ecule is a hydrogen-bond donor to the double-bonded N atom of an adjacent Sciff base, pairs of interactions taking place across a center of symmetry and giving rise to a hydrogen-bonded dimer.
