Abstract: In the hydrazone molecule of the title compound, C₁₃H₉I₂N₃O₂·CH₃CN, the aromatic rings form a dihedral angle of 9.4 (3)°. In the crystal structure, intermolecular IN interactions [3.099 (4) Å] link hydrogen-bonded aggregates of the hydrozone and solvent molecules related by translation along the b axis into chains. An intramolecular O-HN hydrogen bond forms an S(6) ring.
