5-Bromo-1-octylindoline-2,3-dione

Abstract

The title compound, C16H20BrNO2, crystallizes with two molecules in the asymmetric unit. The indoline ring system and the two ketone O atoms are nearly coplanar, with the largest deviations from the mean plane being 0.077 (2) and 0.055 (2) Å in the two molecules. In each molecule, the mean plane through the octyl chain is nearly perpendicular to the mean plane of the indoline ring system, as indicated by the dihedral angles between them of 86.6 (1) and 76.1 (1)°. In the crystal, molecules are linked by week C—H...O hydrogen bonds, forming a three-dimensional network.
