The compound described by CsRbMg6 crystallizes in the orthorhombic Amm2 space group. Cs(1) is bonded to two equivalent Rb(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(3) atoms to form distorted CsRb2Mg10 cuboctahedra that share corners with six equivalent Cs(1)Rb2Mg10 cuboctahedra, edges with four equivalent Rb(1)Cs2Mg10 cuboctahedra, faces with two equivalent Cs(1)Rb2Mg10 cuboctahedra, and faces with two equivalent Rb(1)Cs2Mg10 cuboctahedra. Rb(1) is bonded to two equivalent Cs(1), two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms to form distorted RbCs2Mg10 cuboctahedra that share corners with six equivalent Rb(1)Cs2Mg10 cuboctahedra, edges with four equivalent Cs(1)Rb2Mg10 cuboctahedra, faces with two equivalent Cs(1)Rb2Mg10 cuboctahedra, and faces with two equivalent Rb(1)Cs2Mg10 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 8-coordinate geometry to two equivalent Cs(1), two equivalent Rb(1), one Mg(1), one Mg(2), and two equivalent Mg(4) atoms. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Rb(1), two equivalent Mg(1), two equivalent Mg(4), and four equivalent Mg(3) atoms. In the third Mg site, Mg(3) is bonded in a 8-coordinate geometry to two equivalent Cs(1), two equivalent Rb(1), one Mg(3), one Mg(4), and two equivalent Mg(2) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Cs(1), two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(1) atoms. is represented by the CIF card [CIF]
