Crystal structure of (E)-2,6-di-tert-butyl-4-{[2-(2,4-dinitrophenyl)hydrazinylidene]methyl}phenol

Abstract

The essential part (including all the non-hydrogen atoms except two methyl carbons) of the molecule of the title compound, C21H26N4O5, lies on a mirror plane, which bisects thet-butyl groups. The conformation of the C=N bond of this Schiff base compound isE, and there is an intramolecular N—H...O hydrogen bond present, forming anS(6) ring motif. In the crystal, molecules are linkedviaO—H...O hydrogen bonds, forming zigzag chains propagating along thea-axis direction. There are no other significant intermolecular contacts present.
