, the fused ring system is almost planar [the dihedral angle between the six-membered rings is 1.81 (6)°]. The 2-tolyl ring is approximately orthogonal to this plane [dihedral angle = 83.03 (7)°] as is the acetonitrile group [C—O—C—C torsion angle = 79.24 (14)°] which is also
syn
to the methyl substituent of the tolyl group. In the crystal, supramolecular layers are formed in the
bc
plane mediated by C—H⋯O, C—H⋯N and C—H⋯π interactions. The tolyl group is disordered over two positions in a 0.852 (3):0.148 (3) ratio.
