The structure described by Cs2CoI4 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 9-coordinate geometry to two equivalent I(2), three equivalent I(1), and four equivalent I(3) atoms. In the second Cs site, Cs(2) is bonded in a 7-coordinate geometry to one I(1), two equivalent I(2), and four equivalent I(3) atoms. Co(1) is bonded in a tetrahedral geometry to one I(1), one I(2), and two equivalent I(3) atoms. There are three inequivalent I sites. In the first I site, I(1) is bonded in a 1-coordinate geometry to one Cs(2), three equivalent Cs(1), and one Co(1) atom. In the second I site, I(2) is bonded in a 5-coordinate geometry to two equivalent Cs(1), two equivalent Cs(2), and one Co(1) atom. In the third I site, I(3) is bonded in a distorted single-bond geometry to two equivalent Cs(1), two equivalent Cs(2), and one Co(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
