Crystal structure of 4-phenyl-1-{2-[(2,4,6-trimethylphenyl)selanyl]phenyl}-1H-1,2,3-triazole

In the title compound, C23H21N3Se, the C-bound phenyl ring is almost coplanar with the central five-membered ring [dihedral angle = 2.84 (10)degrees], but the N-bound benzene ring is inclined [dihedral angle = 47.52 (10)degrees]. The dihedral angle between the Se-bound rings is 69.24 (9)degrees. An intramolecular Se center dot center dot center dot N interaction of 3.0248 (15) angstrom is noted. In the crystal, C-H center dot center dot center dot pi interactions connect molecules into double layers that stack along the a axis with no directional interactions between them.
