The material structure described by RbMg6Cd crystallizes in the orthorhombic Amm2 space group. Rb(1) is bonded to two equivalent Mg(2), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Cd(1) atoms to form RbMg10Cd2 cuboctahedra that share corners with six equivalent Rb(1)Mg10Cd2 cuboctahedra, faces with two equivalent Rb(1)Mg10Cd2 cuboctahedra, and faces with six equivalent Mg(4)Mg10Cd2 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 4-coordinate geometry to two equivalent Rb(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and two equivalent Cd(1) atoms. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent Rb(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 10-coordinate geometry to two equivalent Rb(1), one Mg(3), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(4), and one Cd(1) atom. In the fourth Mg site, Mg(4) is bonded to two equivalent Mg(2), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Cd(1) atoms to form distorted MgMg10Cd2 cuboctahedra that share corners with six equivalent Mg(4)Mg10Cd2 cuboctahedra, faces with two equivalent Mg(4)Mg10Cd2 cuboctahedra, and faces with six equivalent Rb(1)Mg10Cd2 cuboctahedra. Cd(1) is bonded in a 10-coordinate geometry to two equivalent Rb(1), two equivalent Mg(3), two equivalent Mg(4), and four equivalent Mg(1) atoms. is represented by the CIF card [CIF]
