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

Abstract

In the title compound, C(21)H(12)ClN(3)O, the phenoxy ring makes dihedral angles of 51.42 (5) and 65.01 (6)degrees, respectively, with the chlorophenyl and phthalonitrile rings. In the crystal structure, the molecules are interlinked through weak C-H center dot center dot center dot N and C-H center dot center dot center dot pi contacts, and pi-pi stacking interactions via crystallographic inversion centres form a three-dimensional network. The distance between the centroids of the phthalonitrile rings is 3.9104 (11)angstrom, with a slippage between the rings of 1.626 angstrom and a perpendicular distance between the rings of 3.556 angstrom.
