| Popis: | In the crystal structure of the title ketoamine, C19H29NO, the bond lengths from the N atom through the alkene group to the ketone O atom show the presence of an extensively delocalized π-system. The dihedral angle between the plane of the phenyl ring and that of the alkene component is 63.45 (7)° due to steric hindrance exerted by the tert-butyl groups. The molecule has a Z-configured alkene function, which is facilitated by an intramolecular N—H...O hydrogen bond between the amine and ketone groups. The molecules are linked into extended chains, which run parallel to the [010] direction, by a very weak C—H...O interaction between the methyl substituent of the alkene group and the ketone O atom of a neighbouring molecule. |
