Crystal structure and Hirshfeld surface analysis of 3-(bromo-meth-yl)-2-[1,2-di-bromo-2-(6-nitro-benzo[][1,3]dioxol-5-yl)eth-yl]-1-(phenyl-sulfon-yl)-1-indole chloro-form 0.585-solvate.

The title indole derivative, CHBrNOS, crystallizes with a partial occupancy [0.585 (4)] CHCl solvent mol-ecule. The dihedral angles between the indole ring system and pendant nitro-benzodioxolane rings system and phenyl-sulfonyl ring are 4.81 (14) and 72.24 (19)°, respectively. In the crystal, the indole mol-ecules are linked to each other and to the chloro-form mol-ecule by weak C-H⋯O, C-H⋯Cl, C-H⋯π, C-Br⋯π and C-Cl⋯π and aromatic π-π stacking inter-actions. A Hirshfeld surface analysis was carried out and the inter-molecular contacts with the most significant contributions are H⋯O/O⋯H (24.3%), H⋯H (18.4%), Br⋯H/H⋯Br (16.8%) and C⋯H/H⋯C (8.4%).
