4-Iodo-1H-indole-2,3-dione

The title compound, C8H4INO2, is an almost planar molecule having an r.m.s. deviation of 0.03 Å for all non-H atoms. In the crystal, molecules dimerize through pairs of N—H...O hydrogen bonds. These inversion dimers are linked through pairs of weak I...O interactions [3.184 (4) Å] to form zigzag cha...

Description
Summary:The title compound, C8H4INO2, is an almost planar molecule having an r.m.s. deviation of 0.03 Å for all non-H atoms. In the crystal, molecules dimerize through pairs of N—H...O hydrogen bonds. These inversion dimers are linked through pairs of weak I...O interactions [3.184 (4) Å] to form zigzag chains along [010]. The chains are linked in the c-axis direction by parallel-slipped π–π interactions [intercentroid distance = 3.623 (3) Å, interplanar distance = 3.423 (2) Å and slippage = 1.667 (5) Å], forming corrugated sheets parallel to (011).
