Extraction and presentation

Rhenium (III) bromide can be obtained by the decomposition of Ag ₂ [ReBr ₆ ] at 450 ° C or the thermal decomposition of rhenium (V) bromide at 650 ° C.

{\ displaystyle {\ ce {2Ag2 [ReBr6] -> 4AgBr + 2ReBr3 + Br2}}}

{\ displaystyle {\ ce {ReBr5 -> ReBr3 + Br2}}}

It is also possible to use rhenium with bromine at 600 ° C.

{\ displaystyle {\ ce {2Re + 3Br2 -> 2ReBr3}}}

properties

Rhenium (III) bromide is a black solid. It stays in air for some time, in the desiccator for months. Its vapor consists mainly of Re ₃ Br ₉ molecules. It is slowly and moderately soluble in acetone , ethanol , and ether. Rapid solvolysis occurs in water (initially purple in the solution), methanol, and liquid ammonia .
