Abstract: As part of an antipsychotic drug discovery program, we report the crystal structure of the title compound, C₂₄H₂₃ClN₄O. The molecule has a tricyclic framework with a characteristic buckled V-shaped pyridobenzoxazepine unit, with the central seven-membered heterocycle in a boat configuration. The piperazine ring displays a chair conformation with the 2-phenyl-ethyl substituent assuming an equatorial orientation. There are two crystallographically independent, but virtually identical, molecules in the asymmetric unit.
