The compound described by CsGeI3 crystallizes in the monoclinic Cm space group. Cs(1) is bonded to four equivalent I(1) and eight equivalent I(2) atoms to form a mixture of face and corner-sharing CsI12 cuboctahedra. Ge(1) is bonded in a 3-coordinate geometry to one I(1) and two equivalent I(2) atoms. There are two inequivalent I sites. In the first I site, I(1) is bonded in a distorted single-bond geometry to four equivalent Cs(1) and one Ge(1) atom. In the second I site, I(2) is bonded in a distorted single-bond geometry to four equivalent Cs(1) and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
