The crystal structure described by RbMg6Sn crystallizes in the orthorhombic Amm2 space group. Rb(1) is bonded to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(2), and two equivalent Sn(1) atoms to form RbMg10Sn2 cuboctahedra that share corners with four equivalent Sn(1)Rb2Mg10 cuboctahedra, corners with six equivalent Rb(1)Mg10Sn2 cuboctahedra, edges with two equivalent Sn(1)Rb2Mg10 cuboctahedra, faces with two equivalent Rb(1)Mg10Sn2 cuboctahedra, and faces with two equivalent Sn(1)Rb2Mg10 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 3-coordinate geometry to two equivalent Rb(1), two equivalent Mg(4), and two equivalent Sn(1) atoms. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one Mg(4), and two equivalent Sn(1) atoms. In the third Mg site, Mg(3) is bonded in a distorted water-like geometry to two equivalent Mg(4) and two equivalent Sn(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Rb(1), two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(1) atoms. Sn(1) is bonded to two equivalent Rb(1), two equivalent Mg(3), four equivalent Mg(1), and four equivalent Mg(2) atoms to form distorted SnRb2Mg10 cuboctahedra that share corners with four equivalent Rb(1)Mg10Sn2 cuboctahedra, corners with six equivalent Sn(1)Rb2Mg10 cuboctahedra, edges with two equivalent Rb(1)Mg10Sn2 cuboctahedra, faces with two equivalent Rb(1)Mg10Sn2 cuboctahedra, and faces with two equivalent Sn(1)Rb2Mg10 cuboctahedra. is represented by the CIF card [CIF]
