The crystal structure described by Sm2OI2 is Cyanogen Chloride-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Sm2OI2 cluster. Sm(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 Sm(1) atoms. I(1) is bonded in a single-bond geometry to one Sm(1) atom. is represented by the CIF file [CIF]
