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

In the title compound, C21H17N3OSe, the dihedral angles between the central five-membered ring and the C- and N-bound rings are 17.89 (10) and 42.35 (10)degrees, respectively, indicating the molecule is twisted. The dihedral angle between the Se-bound rings is 85.36 (10)degrees. A close intramolecular Se center dot center dot center dot O contact of 2.8507 (13) angstrom is noted. In the crystal, C-H center dot center dot center dot O, C-H center dot center dot center dot N and C-H center dot center dot center dot pi interactions lead to the formation of supramolecular layers parallel to (011); these stack with no specific intermolecular interactions between them.
