Antimony tribromide - Wikipedia

Antimony tribromide has two crystalline forms, both having orthorhombic symmetries. When a warm carbon disulfide solution of SbBr 3 is rapidly cooled, it crystallizes into the needle-like α-SbBr 3, which then slowly converts to the more stable β form. Antimony tribromide hydrolyzes in water to form hydrobromic acid and antimony trioxide: 2 ...
