RbGeI3 crystallizes in the orthorhombic P2_12_12_1 space group. Rb(1) is bonded in a 9-coordinate geometry to two equivalent I(1), three equivalent I(2), and four equivalent I(3) atoms. Ge(1) is bonded in a 3-coordinate geometry to one I(1), one I(2), and one I(3) atom. There are three inequivalent I sites. In the first I site, I(1) is bonded in a 2-coordinate geometry to two equivalent Rb(1) and one Ge(1) atom. In the second I site, I(2) is bonded in a distorted see-saw-like geometry to three equivalent Rb(1) and one Ge(1) atom. In the third I site, I(3) is bonded to four equivalent Rb(1) and one Ge(1) atom to form a mixture of distorted corner and edge-sharing IRb4Ge square pyramids.
