The molecular structure of the title compound, C11H13IN4O3, shows a ribofuranosyl–pyrrolo O—C—N—C torsion angle of 59.1 (3)°, with the central C—N bond length being 1.446 (3) Å. The C—I bond length is 2.072 (2) Å. The amino group is coplanar with the attached aromatic ring [C—N—C—N torsion angle = −178.8 (2)°] and forms an intramolecular N—H...I hydrogen bond. In the crystal, O—H...N and N—H...O hydrogen bonds link the molecules into puckered layers parallel to (001). These layers are bound to each other by secondary I...O interactions [3.2250 (17) Å], forming a three-dimensional framework.
