Specification
Yttrium(III) chloride 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
