2-Hydroxy-3-methoxybenzaldehyde 2,4-dinitrophenylhydrazone pyridine monosolvate

Abstract

The Schiff base molecule of the title compound, C14H12N4O6·C5H5N, was obtained from the condensation reaction of 2-hydroxy-3-methoxybenzaldehyde and 2,4-dinitrophenylhydrazine. The C=N bond of the Schiff base has a trans arrangement and the dihedral angle between the two benzene rings is 3.49 (10)°. An intramolecular N—H...O hydrogen bond generates an S(6) ring. In the crystal, O—H...O hydrogen bonds link the Schiff base molecules.
