Abstract: The asymmetric unit of the title compound, C13H11IN2O, comprises two crystallographically independent molecules. The dihedral angles between the ring planes are 53.56 (9) and 72.14 (19)° in the two molecules. Pairs of intermolecular N-HN hydrogen bonds and IO interactions link neighbouring molecules into two different pairs of dimers, those involving N-HN interactions having R22(8) ring motifs. Short intermolecular IO [3.1458 (15) Å] and IN [3.4834 (16) Å] contacts are present. The crystal structure is further stabilized by intermolecular C-H interactions [3.565 (2) and 3.629 (2) Å].
