The title mol-ecule, C(16)H(15)I(2)N(3)O(2), adopts an E configuration about the C=N bond. The dihedral angle between the two benzene rings is 6.4 (2)°. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains propagating in the c-axis direction.
