Abstract
In the title compound, C14H9ClI2N2O2, the dihedral angle between the benzene rings is 65.9 (2)° and an intramolecular O—H⋯N hydrogen bond generates an S(6) ring. The molecule has an E conformation about the C=N bond. In the crystal, molecules are linked into C(4) chains propagating in [001] by N—H⋯O hydrogen bonds.
