Yttrium(III) Chloride

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. 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 .
