Crystal structure of (E)-2-(tert-butyl­amino)-4-(tert-butyl­imino)­naphthalen-1(4H)-one

The title compound, C18H24N2O, is the first example of a naphtho­quinone imine derivative isolated in the 4-imine/2-amine tautomeric form having bulky alkyl substituents at the N atoms. The mol­ecular conformation is stabilized by an intra­molecular hydrogen bond between the amine and a carbonyl group and by London attraction between the two tert-butyl groups. Only van der Waals inter­actions were identified in the crystal packing.
