Plutonium(III) bromide is an inorganic salt of bromine and plutonium with the formula PuBr₃. This radioactive green solid has few uses, however its crystal structure is often used as a structural archetype in crystallography.

Crystal structure

Unit cell

PuBr₃: Pu³⁺ Br⁻

The PuBr₃ crystal structure was first published in 1948 by William Houlder Zachariasen.^[2] The compound forms orthorhombic crystals, a type of square antiprism, within which the Pu atoms adopt an 8-coordinate bicapped trigonal prismatic arrangement. Its Pearson symbol is oS16 with the corresponding space group No. 63 (in International Union of Crystallography classification) or Cmcm (in Hermann–Mauguin notation).
