The structure described by RbNaMg6 crystallizes in the orthorhombic Amm2 space group. Rb(1) is bonded to two equivalent Na(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(3) atoms to form a mixture of face and corner-sharing RbNa2Mg10 cuboctahedra. Na(1) is bonded in a 10-coordinate geometry to two equivalent Rb(1), two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 11-coordinate geometry to two equivalent Rb(1), two equivalent Na(1), one Mg(1), two equivalent Mg(2), two equivalent Mg(3), and two equivalent Mg(4) atoms. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent Na(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(3) atoms. In the third Mg site, Mg(3) is bonded in a 4-coordinate geometry to two equivalent Rb(1), two equivalent Na(1), two equivalent Mg(1), two equivalent Mg(2), and two equivalent Mg(4) atoms. In the fourth Mg site, Mg(4) is bonded in a 12-coordinate geometry to two equivalent Rb(1), two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms. is represented by the CIF file [CIF]
