Abstract: In the title compound, C₁₁H₁₀INO₃, an addition product of itaconic acid anhydride and 4-iodoaniline, the least-squares planes defined by the atoms of the aromatic moiety and the non-H atoms of the carboxylic acid group enclose an angle of 74.82 (11)°. In the crystal, classical O-HO hydrogen bonds formed by carboxylic groups, as well as N-HO hydrogen bonds formed by amide groups, are present along with C-HO contacts. Together, these connect the molecules into dimeric chains along the b-axis direction.
