The compound described by 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. is represented by the CIF file [CIF]
