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]
