RbGe3 crystallizes in the hexagonal P6_3/mmc space group. Rb(1) is bonded in a 12-coordinate geometry to twelve equivalent Ge(1) atoms. Ge(1) is bonded in a 10-coordinate geometry to four equivalent Rb(1) and six equivalent Ge(1) atoms.
RbGe3 crystallizes in the hexagonal P6_3/mmc space group. Rb(1) is bonded in a 12-coordinate geometry to twelve equivalent Ge(1) atoms. There are six shorter (3.74 Å) and six longer (3.81 Å) Rb(1)-Ge(1) bond lengths. Ge(1) is bonded in a 10-coordinate geometry to four equivalent Rb(1) and six equivalent Ge(1) atoms. There are two shorter (2.65 Å) and four longer (2.91 Å) Ge(1)-Ge(1) bond lengths.
