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.
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. There are a spread of Cs(1)-I(1) bond distances ranging from 4.22-4.36 Å. There are a spread of Cs(1)-I(2) bond distances ranging from 4.21-4.43 Å. Ge(1) is bonded in a 3-coordinate geometry to one I(1) and two equivalent I(2) atoms. The Ge(1)-I(1) bond length is 2.74 Å. Both Ge(1)-I(2) bond lengths are 2.75 Å. 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.
