Plutonium oxybromide is an inorganic compound of plutonium, oxygen, and bromine with the chemical formula PuOBr. [2] [3] [4] [5]

Contents

Synthesis

The compound was first observed by Davidson et al. in 1949 as a residue from the sublimation of small amounts of PuBr3 in a silica tube. Pure PuOBr can be obtained by treating plutonim(IV) hydroxide with moist hydrogen bromide at 750 °C. [6]

It is also produced in the reaction between plutonium dioxide and hydrogen bromide: [7]

PuO2 + ½H2 + HBr → PuOBr + H2O

Physical properties

Plutonium oxybromide forms dark green crystals of tetragonal system, space group P4/nmm. [8]

Chemical properties

The compound reacts with dilute acids: [9]

PuOBr + 2HBr → PuBr3 + H2O
