Sr2OI2 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a distorted L-shaped geometry to two equivalent O(1) and five equivalent I(1) atoms. O(1) is bonded to four equivalent Sr(1) atoms to form distorted edge-sharing OSr4 tetrahedra. I(1) is bonded in a 5-coordinate geometry to five equivalent Sr(1) atoms.
Sr2OI2 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a distorted L-shaped geometry to two equivalent O(1) and five equivalent I(1) atoms. Both Sr(1)-O(1) bond lengths are 2.39 Å. There are a spread of Sr(1)-I(1) bond distances ranging from 3.41-3.69 Å. O(1) is bonded to four equivalent Sr(1) atoms to form distorted edge-sharing OSr4 tetrahedra. I(1) is bonded in a 5-coordinate geometry to five equivalent Sr(1) atoms.
