RESUMO
In the title compound, C26H24N2O2, the oxazine moiety is fused to a naphthalene ring system. The asymmetric unit consists of one half of the mol-ecule, which lies about an inversion centre. The C atoms of the ethyl-ene spacer group adopt an anti-periplanar arrangement. The oxazine ring adopts a half-chair conformation. In the crystal, supra-molecular chains running along the b axis are formed via short C-Hâ¯π contacts. The crystal studied was a non-merohedral twin with a fractional contribution of 0.168â (2) of the minor twin component.
