1-[(4-Chlorophenyl)(phenylimino)methyl]-7-methoxy-2-naphthol–1,4-diazabicyclo[2.2.2]octane (2/1)

In the crystal structure of the title cocrystal, 2C24H18ClNO2·C6H12N2, the 1,4-diazabicyclo[2.2.2]octane molecule is located on a twofold rotation axis and linked to the two triarylimine molecules by O—H...N hydrogen bonds, forming a 2:1 aggregate. C—H...Cl interactions are also observed. In the triarylimine molecule, the naphthalene ring system makes dihedral angles of 80.39 (6) and 82.35 (6)°, respectively, with the phenyl and benzene rings. The dihedral angle between these two latter rings is 87.09 (7)°.
