The crystal structure described by RbMg6Fe crystallizes in the orthorhombic Amm2 space group. Rb(1) is bonded to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Fe(1) atoms to form RbMg10Fe2 cuboctahedra that share corners with four equivalent Mg(4)Rb2Mg10 cuboctahedra, corners with six equivalent Rb(1)Mg10Fe2 cuboctahedra, edges with two equivalent Mg(4)Rb2Mg10 cuboctahedra, faces with two equivalent Rb(1)Mg10Fe2 cuboctahedra, and faces with two equivalent Mg(4)Rb2Mg10 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 1-coordinate geometry to two equivalent Rb(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and one Fe(1) atom. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Fe(1) atoms. In the third Mg site, Mg(3) is bonded in a 11-coordinate geometry to two equivalent Rb(1), one Mg(3), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(4), and two equivalent Fe(1) atoms. In the fourth Mg site, Mg(4) is bonded to two equivalent Rb(1), two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms to form distorted MgRb2Mg10 cuboctahedra that share corners with four equivalent Rb(1)Mg10Fe2 cuboctahedra, corners with six equivalent Mg(4)Rb2Mg10 cuboctahedra, edges with two equivalent Rb(1)Mg10Fe2 cuboctahedra, faces with two equivalent Rb(1)Mg10Fe2 cuboctahedra, and faces with two equivalent Mg(4)Rb2Mg10 cuboctahedra. Fe(1) is bonded in a 10-coordinate geometry to two equivalent Rb(1), two equivalent Mg(1), two equivalent Mg(2), and four equivalent Mg(3) atoms. is represented by the CIF card [CIF]
