5,6-Dibromo-1H-indole-2,3-dione

The title compound, C8H3Br2NO2, crystallizes with two near planar molecules in the asymmetric unit, with non-H atoms possessing mean deviations from planarity of 0.012 and 0.014 Å. The two molecules are connected by an N—H...O and a C—H...O hydrogen bond. In the crystal, molecules connect through a...

Description
Summary:The title compound, C8H3Br2NO2, crystallizes with two near planar molecules in the asymmetric unit, with non-H atoms possessing mean deviations from planarity of 0.012 and 0.014 Å. The two molecules are connected by an N—H...O and a C—H...O hydrogen bond. In the crystal, molecules connect through a series of bifurcated N—(H,H)...O hydrogen bonds, forming chains propagating along the [1-1-1] direction. The molecules are further linked through intermolecular halogen interactions, including a Br...O close contact of 2.9409 (3) Å, and two C—H...Br interactions of 3.777 (3) and 3.845 (3) Å. These interactions link the chains into sheets lying parallel to the (1-23) plane.
