3-Ethoxy-2-hydroxybenzaldehyde 2,4-dinitrophenylhydrazone N,N-dimethylformamide monosolvate

By Lin-xiu Zhao, Jian-lan Cui and Duan-lin Cao


The Schiff base of the title compound, C15H14N4O6·C3H7NO, was obtained from the condensation reaction of 3-ethoxy-2-hydroxybenzaldehyde and 2,4-dinitrophenylhydrazine. The dihedral angle between the benzene rings is 3.05 (10)° and intramolecular N—H...O and O—H...O hydrogen bonds generate S(6) and S(5) ring motifs, respectively. In the crystal, the Schiff base and dimethylformamide solvent molecules are linked by an O—H...O hydrogen bond
