Thulium dibromide is aninorganic compound, with thechemical formula of TmBr2. It is a dark green solid that is easy to dissolve, with theSrI2 structure and it needs to be stored in an inert atmosphere.
Thulium dibromide can be prepared by reactingthulium withthulium tribromide at 800~900 °C in a vacuum.[1] At high temperatures, the alkali metals can also obtain bromide, but only lithium and sodium reactions obtain thulium dibromide, and the response to the participation ofpotassium,rubidium, andcaesium.[2]
