    “…The two benzene rings make a dihedral angle of 86.40 (2)° with each other. The 1,3-oxazepine C atom to which the 4-chloro­phenyl group is attached and the C atom of the 4-chloro­phenyl group attached to the 1,3-oxazepine ring are chiral C atoms, but the crystal is a racemate in which the enanti­omers are linked by a pair of weak inter­molecular C—H⋯O hydrogen bond, forming an inversion dimer.…”
