The structure described by KMg6La crystallizes in the orthorhombic Amm2 space group. K(1) is bonded to two equivalent Mg(2), four equivalent Mg(1), four equivalent Mg(3), and two equivalent La(1) atoms to form KLa2Mg10 cuboctahedra that share corners with six equivalent K(1)La2Mg10 cuboctahedra, edges with four equivalent La(1)K2Mg10 cuboctahedra, faces with two equivalent K(1)La2Mg10 cuboctahedra, and faces with two equivalent La(1)K2Mg10 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 12-coordinate geometry to two equivalent K(1), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and two equivalent La(1) atoms. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent K(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 K(1), one Mg(3), one Mg(4), two equivalent Mg(1), two equivalent Mg(2), and two equivalent La(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 8-coordinate geometry to two equivalent Mg(2), two equivalent Mg(3), four equivalent Mg(1), and two equivalent La(1) atoms. La(1) is bonded to two equivalent K(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(3) atoms to form LaK2Mg10 cuboctahedra that share corners with six equivalent La(1)K2Mg10 cuboctahedra, edges with four equivalent K(1)La2Mg10 cuboctahedra, faces with two equivalent K(1)La2Mg10 cuboctahedra, and faces with two equivalent La(1)K2Mg10 cuboctahedra. is represented by the CIF file [CIF]
