Abstract
The title compound [systematic name: 5-(trifluoromethoxy)-1H-indole-2,3-dione], C9H4F3NO3, crystallized with two molecules in the asymmetric unit. Intermolecular N—H...O hydrogen bonds link the molecules to form layers parallel to the ab plane. In addition, π–π stacking interactions are observed with a centroid–centroid distance of 3.721 (1) Å. The near planarity of the two isatin ring systems is illustrated by by the maximum deviations of 0.023 (1) and 0.025 (1) Å for the N atom in each case.
