Chemical compound
Thulium dibromide is an inorganic compound, with the chemical formula of TmBr2. It is a dark green solid that is easy to dissolve, with the SrI2 structure and it needs to be stored in an inert atmosphere.
Preparation
[edit ]Thulium dibromide can be prepared by reacting thulium with thulium 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 of potassium, rubidium, and caesium.[2]
