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)°, respectively, indicating the molecule is twisted. The dihedral angle between the Se-bound rings is 85.36 (10)°. A close intramolecular Se⋯O contact of 2.8507 (13) Å is noted. In the crystal, C—H⋯O, C—H⋯N and C—H⋯π interactions lead to the formation of supramolecular layers parallel to (011); these stack with no specific intermolecular interactions between them.
Keywords: crystal structure; organoselenium; Se⋯O halogen bonding; hydrogen bonding; C—H⋯π interactions.

The compound was prepared in accord with the literature (Deobald et al., 2011). Crystals were obtained by taking 200 mg of sample into a sample vial containing methanol (10 ml) and letting it stand at room temperature.
Carbon-bound H-atoms were placed in calculated positions (C—H = 0.95 to 0.98 Å) and were included in the
in the riding model approximation, with Uiso(H) = 1.2–1.5Ueq(C).Data collection: CrysAlis PRO (Agilent, 2011); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
