The compound described by CsMg6La crystallizes in the orthorhombic Amm2 space group. Cs(1) is bonded in a 8-coordinate geometry to two equivalent Mg(1), two equivalent Mg(4), four equivalent Mg(2), and two equivalent La(1) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 7-coordinate geometry to one Cs(1), one Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and one La(1) atom. In the second Mg site, Mg(2) is bonded in a 8-coordinate geometry to two equivalent Cs(1), one Mg(2), one Mg(4), two equivalent Mg(1), and two equivalent La(1) atoms. In the third Mg site, Mg(3) is bonded in a 6-coordinate geometry to four equivalent Mg(1) and two equivalent La(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Cs(1), two equivalent Mg(2), four equivalent Mg(1), and two equivalent La(1) atoms. La(1) is bonded to two equivalent Cs(1), two equivalent Mg(1), two equivalent Mg(3), two equivalent Mg(4), and four equivalent Mg(2) atoms to form a mixture of distorted face and corner-sharing LaCs2Mg10 cuboctahedra. is represented by the CIF file [CIF]
