RbGeBr3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pna2_1 space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Br(3), three equivalent Br(1), and three equivalent Br(2) atoms. Ge(1) is bonded in a distorted T-shaped geometry to one Br(1), one Br(2), and one Br(3) atom. There are three inequivalent Br sites. In the first Br site, Br(1) is bonded in a distorted see-saw-like geometry to three equivalent Rb(1) and one Ge(1) atom. In the second Br site, Br(2) is bonded in a 4-coordinate geometry to three equivalent Rb(1) and one Ge(1) atom. In the third Br site, Br(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Rb(1) and one Ge(1) atom.
