Abstract
The asymmetric unit of the title compound, C17H14N2O2, consists of two independent molecules differing mainly in the orientations of the phenyl and oxirane substituents. In the first molecule, the dihedral angle between the dihydroquinoxaline ring system and phenyl ring is 28.4 (2)° and the N—C—C—O torsion angle is 87.8 (5)°; corresponding data for the second molecule are 23.1 (2) and −85.6 (5)°, respectively. In the crystal, offset π-stacking interactions between the dihydroquinoxaline moieties form oblique stacks, which are connected into layers parallel to the bc plane by C—H...O hydrogen bonds and C—H...π(ring) interactions. Additional C—H...π(ring) interactions tie the layers together. The model was refined as a two-component twin.
