2-Tert-Butyl-4-Methyl-6-(Phenyl­diazenyl)­phenol

Abstract

The crystal structure of the title compound, C<inf>17</inf>H <inf>20</inf>N<inf>2</inf>O, determined at 208 K, shows that the molecule is approximately planar in the solid state, having a trans configuration with respect to the azo double bond, as found for other diazene derivatives. The dihedral angle between the planes of the two aromatic rings is 5.04 (12)°. The hydroxy group and an N atom of the azo group are linked by an intramolecular O - H⋯N hydrogen bond. © 2003 International Union of Crystallography Printed in Great Britain - all rights reserved.
