The crystal structure described by CsOIF4 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 11-coordinate geometry to three equivalent O(1), four equivalent F(1), and four equivalent F(2) atoms. O(1) is bonded in a single-bond geometry to three equivalent Cs(1) and one I(1) atom. I(1) is bonded in a square pyramidal geometry to one O(1), two equivalent F(1), and two equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one I(1) atom. In the second F site, F(2) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one I(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
