2-(Adamantan-1-yl)-5-(4-nitro-phen-yl)-1,3,4-oxadiazole

Abstract

The title mol-ecule, C(18)H(19)N(3)O(3), lies on a mirror plane that bis-ects the adamantyl group. In the crystal, C-H⋯O and C-H⋯N inter-actions lead to supra-molecular chains along [100]. These assemble into layers in the ab plane via π-π inter-actions [centroid-centroid distance = 3.6548 (7) Å] between the oxadiazole and benzene rings.
