4,6-Di-tert-butyl-2-({[4-(diethylamino)phenyl]imino}methyl)phenol

Abstract

The title compound, C25H36N2O, adopts anEconformation about the C=N bond. The dihedral angle between the aromatic rings is 35.6 (6)°. The molecular structure is stabilized by an O—H...N hydrogen bond, which forms anS(6) loop, and weak C—H...O contacts. Weak intermolecular C—H...π interactions are observed in the crystal packing. The diethylamino group has rotational disorder with site occupancies of 0.85 (2) and 0.15 (2) for the major and minor components, respectively. The structure was refined as a three-component twin.
