Er2OI2 is Cyanogen Chloride-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Er2OI2 cluster. Er(1) is bonded in a distorted linear geometry to one O(1) and one I(1) atom. O(1) is bonded in a linear geometry to two equivalent Er(1) atoms. I(1) is bonded in a single-bond geometry to one Er(1) atom.
