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

Abstract

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