2-{[3-Chloro-4-(4-chlorophenoxy)phenyl]iminomethyl}-4-nitrophenol

Abstract

In the title compound, C19H12Cl2N2O4, the imine bond length of 1.257 (6) Å is typical of a double bond. The dihedral angle between the para-nitro benzene ring and the central benzene ring is 12.06 (3)° and that between the central benzene and the para-chloro benzene ring is 73.81 (2)°. An intramolecular O—H...N hydrogen bond generates an S(6) ring motif. In the crystal, molecules are linked together by two pairs of C—H...O interactions (to the same O atom acceptor), forming inversion dimers. A short Cl...Cl contact [3.232 (4) Å] is observed.
