Bismuth bromide, BiBr3, is the only well-characterized bromide of bismuth. It is formed by direct reaction of the elements.[3] The gas phase molecule is pyramidal, with r(Bi–Br) = 256.7(5) pm and θ(Br–Bi–Br) = 98.6(2)°.[4] It is dimorphic in the solid state, with the α-phase retaining pyramidal BiBr3 units (mean r(Bi–Br) = 266.3 pm) while the β-phase shows octahedral coordination for the bismuth (mean r(Bi–Br) = 281 pm).[5] It has a number of specialist uses.[6]
