The structure described by CaMg6La crystallizes in the orthorhombic Amm2 space group. Ca(1) is bonded to two equivalent Mg(3), four equivalent Mg(1), four equivalent Mg(2), and two equivalent La(1) atoms to form distorted CaLa2Mg10 cuboctahedra that share corners with four equivalent La(1)Ca2Mg10 cuboctahedra, corners with six equivalent Ca(1)La2Mg10 cuboctahedra, edges with two equivalent La(1)Ca2Mg10 cuboctahedra, faces with two equivalent Ca(1)La2Mg10 cuboctahedra, and faces with two equivalent La(1)Ca2Mg10 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to two equivalent Ca(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 4-coordinate geometry to two equivalent Ca(1), one Mg(3), two equivalent Mg(1), two equivalent Mg(4), and two equivalent La(1) atoms. In the third Mg site, Mg(3) is bonded in a 8-coordinate geometry to two equivalent Ca(1), two equivalent Mg(2), and four equivalent Mg(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to four equivalent Mg(1), four equivalent Mg(2), and two equivalent La(1) atoms. La(1) is bonded to two equivalent Ca(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(2) atoms to form distorted LaCa2Mg10 cuboctahedra that share corners with four equivalent Ca(1)La2Mg10 cuboctahedra, corners with six equivalent La(1)Ca2Mg10 cuboctahedra, edges with two equivalent Ca(1)La2Mg10 cuboctahedra, faces with two equivalent Ca(1)La2Mg10 cuboctahedra, and faces with two equivalent La(1)Ca2Mg10 cuboctahedra. is represented by the CIF file [CIF]
