In the title compound, C15H12I2N2O4·CH3OH, the hydrazone mol­ecule exists in an E conformation with respect to the C=N bond. The dihedral angle between the rings is 11.9 (2)°. There is one intra­molecular O—H⋯N hydrogen bond in the hydrazone mol­ecule. In the crystal, the hydrazone and methanol mol­ecules are linked through O—H⋯O and N—H⋯O hydrogen bonds and C—H⋯O inter­actions to form two-dimensional networks lying parallel to (001).
