The Sb^V atom in the title compound, [SbCl₂(C₆H₄Br)₃], has an almost regular trigonal-bipyramidal geometry with the equatorial plane made up of three C atoms of the bromophenyl groups and the axial positions occupied by two Cl^- ions in a trans configuration. In the crystal, C-HBr hydrogen bonds link the molecules into zigzag chains along the b-axis direction. Pairs of C-HCl hydrogen bonds further link molecules into cyclic dimers with R₂²(10) ring motifs, generating a three-dimensional network.
