title: Crystal and geometry-optimized structure, and Hirshfeld surface analysis of 1-(2-bromo-eth-yl)indoline-2,3-dione.
abstract: In the title compound, C10H8BrNO2, the isatin (1H-indole-2,3-dione) moiety is nearly planar (r.m.s. deviation = 0.026 Å). In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming layers parallel to theabplane, and enclosingR44(24) loops. There are a low percentage (19.3%) of inter-molecular H⋯H contacts in the structure, as estimated by the analysis of Hirshfeld surfaces. This could be due to the presence of the Br atom, present in the bromo-ethyl-ene group, which makesca18.7% Br⋯H contacts.
