1-(Prop-2-yn-yl)indoline-2,3-dione.

ABSTRACT: The structure of the title compound, C11H7NO2, is isotypic to that of its homologue, 1-octylindoline-2,3-dione [Qachchachi et al. (2013 ?). Acta Cryst. E69, o1801]. The indoline ring and the two carbonyl O atoms are approximately coplanar, the largest deviation from the mean plane being 0.021?(1)?Å for one of the O atoms. The mean plane through the fused ring system is nearly perpendicular to the propynyl group, as indicated by the N-C-C-C torsion angle of 77.9?(1)°. In the crystal, mol-ecules are linked by C-H?O hydrogen bonds and ?-? inter-actions between benzene rings [inter-centroid distance = 3.5630?(10)?Å], forming a three-dimensional structure.
