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 the t-butyl groups. The conformation of the C=N bond of this Schiff base compound is E, and there is an intramolecular N—H...O hydrogen bond present, forming an S(6) ring motif. In the crystal, molecules are linked via O—H...O hydrogen bonds, forming zigzag chains propagating along the a-axis direction. There are no other significant intermolecular contacts present.
