Plutonium oxybromide is an inorganic compound of plutonium, oxygen, and bromine with the chemical formula .
Synthesis The compound was first observed by Davidson et al. in 1949 as a residue from the sublimation of small amounts of in a silica tube. Pure PuOBr can be obtained by treating plutonim(IV) hydroxide with moist hydrogen bromide at 750 °C.
It is also produced in the reaction between plutonium dioxide and hydrogen bromide:
Physical properties Plutonium oxybromide forms dark green crystals of tetragonal system, space group P4/nmm.
Chemical properties The compound reacts with dilute acids:Lemire, R. J. et al., Chemical Thermodynamics of Neptunium and Plutonium, Elsevier, Amsterdam, 2001.
