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.
