Crystal structure of bromido­bis­(naph­thal­en-1-yl)anti­mony(III)

In the title compound, [SbBr(C₁₀H₇)₂], the Sb^III atom has a distorted trigonal–pyramidal coordination geometry and the planes of the two naphthalene ring systems make a dihedral angle of 80.26 (18)°. An intra­molecular C—H...Br hydrogen bond forms an S(5) ring motif. In the crystal, weak C—H...Br inter­actions link the mol­ecules into helical chains along the b-axis direction.
