The asymmetric unit of the title compound, C 13H 8ClI 2NO, contains half of the mol-ecule situated on a mirror plane. The hy-droxy group is involved in the formation of an intra-molecular O - H⋯N hydrogen bond. π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.629 (3) Å] form stacks along the b axis. In the crystal, weak C - H⋯O and C - H⋯Cl inter-actions are observed.

The title compound, C 13H 8BrI 2NO, was prepared by the reaction of 3,5-diiodo-salicyl-aldehyde with 4-bromo-phenyl-amine in ethanol. There is an intra-molecular O - H⋯N hydrogen bond in the mol-ecule, which generates an S(6) ring. The dihedral angle between the benzene rings is 2.6 (3)°.
