3-(2,3-Dioxoindolin-1-yl)propane-nitrile.

ABSTRACT: The asymmetric unit of the title compound, C11H8N2O2, contains two independent mol-ecules (A and B). Each mol-ecule is build up from fused five- and six-membered rings with the former linked to a cyano-ethyl group. The indoline ring and two carbonyl O atoms of each mol-ecule are nearly coplanar, with the largest deviations from the mean planes being 0.0198?(9) (mol-ecule A) and 0.0902?(9)?Å (mol-ecule B), each by a carbonyl O atom. The fused ring system is nearly perpendicular to the mean plane passing through the cyano-ethyl chains, as indicated by the dihedral angles between them of 69.72?(9) (mol-ecule A) and 69.15?(9)° (mol-ecule B). In the crystal, mol-ecules are linked by C-H?O and ?-? [inter-centroid distance between inversion-related indoline (A) rings = 3.6804?(7)?Å] inter-actions into a double layer that stacks along the a-axis direction.
