The asymmetric unit of the title compound, C 19 H 18 I 4 N 2 O 2 , comprises a potentially tetra­dentate Schiff base ligand. The disordered H atoms on the N and O atoms were refined with site occupancies of 0.54 (8)/0.46 (8) and 0.59 (7)/0.41 (7), respectively. The dihedral angle between the benzene rings is 73.3 (3)°. Intra­molecular O—H⋯N and N—H⋯O hydrogen bonds make  S (6) ring motifs. Short I⋯I [3.8919 (7) Å] and I⋯ Cg  [ Cg  is a ring centroid; 3.911 (2) Å] contacts are present in the crystal structure. The crystal structure is further stabilized by inter­molecular π–π inter­actions [centroid-to-centroid distance = 3.827 (3) Å].
