Infobox references

Thulium(II) chloride is an inorganic compound with the chemical formula TmCl2.

## Production

Thulium(II) chloride can be produced by reducing thulium(III) chloride by thulium metal:[1]

2 TmCl3 \+ Tm → 3 TmCl2

## Chemical properties

Thulium(II) chloride reacts with water violently, producing hydrogen gas and thulium(III) hydroxide. When thulium(II) chloride first touches water, a light red solution is formed, which fades quickly.[1]
