【 摘 要 】

In the title compound, C26H24N2O2, the oxazine moiety is fused to a naphthalene ring system. The asymmetric unit consists of one half of the mol­ecule, which lies about an inversion centre. The C atoms of the ethyl­ene spacer group adopt an anti­periplanar arrangement. The oxazine ring adopts a half-chair conformation. In the crystal, supra­molecular chains running along the b axis are formed via short C—H⋯π contacts. The crystal studied was a non-merohedral twin with a fractional contribution of 0.168 (2) of the minor twin component.
