The compound described by SrH2OI2 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 2-coordinate geometry to two equivalent O(1), three equivalent I(2), and four equivalent I(1) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a distorted water-like geometry to two equivalent Sr(1), one H(1), and one H(2) atom. There are two inequivalent I sites. In the first I site, I(1) is bonded to four equivalent Sr(1) atoms to form a mixture of distorted corner and edge-sharing ISr4 tetrahedra. In the second I site, I(2) is bonded in a 3-coordinate geometry to three equivalent Sr(1) atoms. is represented by the CIF card [CIF]
