(E)-4-{2-[(4-Chlorophenyl)iminomethyl]phenoxy}phthalonitrile

Abstract

In the title compound, C21H12ClN3O, the phenoxy ring makes dihedral angles of 51.42 (5) and 65.01 (6)°, respectively, with the chlorophenyl and phthalonitrile rings. In the crystal structure, the molecules are interlinked through weak C—H...N and C—H...π contacts, and π–π stacking interactions via crystallographic inversion centres form a three-dimensional network. The distance between the centroids of the phthalonitrile rings is 3.9104 (11)Å, with a slippage between the rings of 1.626 Å and a perpendicular distance between the rings of 3.556 Å.
