Thulium(III) chloride or thulium trichloride is as an inorganic salt composed of thulium and chlorine with the formula TmCl₃. It forms yellow crystals. Thulium(III) chloride has the YCl₃ (AlCl₃) layer structure with octahedral thulium ions.^[5]

Reactions[]

The hydrated form of thulium(III) chloride can be obtained by adding thulium(III) oxide to concentrated hydrochloric acid.^[1] Thulium(III) chloride reacts with strong bases to make thulium(III) oxide.
