RbNa3 crystallizes in the hexagonal P6_3/mmc space group. Rb(1) is bonded to twelve equivalent Na(1) atoms to form a mixture of distorted face and corner-sharing RbNa12 cuboctahedra. Na(1) is bonded in a 10-coordinate geometry to four equivalent Rb(1) and six equivalent Na(1) atoms.
RbNa3 crystallizes in the hexagonal P6_3/mmc space group. Rb(1) is bonded to twelve equivalent Na(1) atoms to form a mixture of distorted face and corner-sharing RbNa12 cuboctahedra. There are six shorter (4.27 Å) and six longer (4.33 Å) Rb(1)-Na(1) bond lengths. Na(1) is bonded in a 10-coordinate geometry to four equivalent Rb(1) and six equivalent Na(1) atoms. There are two shorter (3.70 Å) and four longer (3.84 Å) Na(1)-Na(1) bond lengths.
