Plutonium oxybromide is an inorganic compound of plutonium, oxygen, and bromine with the chemical formula PuOBr.[2][3][4][5]
Synthesis
The compound was first observed by Davidson et al. in 1949 as a residue from the sublimation of small amounts of PuBr
3 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]
- PuO
2 + ½H
2 + HBr → PuOBr + H
2O
- PuO
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 → PuBr
3 + H
2O
- PuOBr + 2HBr → PuBr
