The structure described by SrOI2 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 2-coordinate geometry to two equivalent O(1) and four equivalent I(1) atoms. O(1) is bonded in a trigonal planar geometry to two equivalent Sr(1) and one I(2) atom. There are two inequivalent I sites. In the first I site, I(2) is bonded in a distorted single-bond geometry to one O(1) and one I(1) atom. In the second I site, I(1) is bonded in a 5-coordinate geometry to four equivalent Sr(1) and one I(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
