摘要

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, mol­ecules are linked by C—H⋯O hydrogen bonds, forming layers parallel to the ab plane, and enclosing R44(24) loops. There are a low percentage (19.3%) of inter­molecular 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 bromo­ethyl­ene group, which makes ca 18.7% Br⋯H contacts.
