Yttrium(III) chloride (YCl3) is an ionic compound of yttrium and chlorine. It is a salt that is solid at room temperature, highly soluble in water, and deliquescent. YCl3 in the solid state has a crystal structure with cubic close packed chloride ions and yttrium ions filling one third of the octahedral holes and the resulting YCl6 octahedra sharing three edges with adjacent octahedra give a layer structure.[3] This structure is shared by a range of compounds notably AlCl3.
YCl3 is used as a catalyst and in superconductors and has been linked to pulmonary edema and liver damage

Reactions
Yttrium(III) chloride can be formed by reacting yttrium(III) oxide with hydrochloric acid,[5] among other methods.[2]
