The structure described by Mg6LaMo crystallizes in the orthorhombic Amm2 space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 12-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), two equivalent La(1), and two equivalent Mo(1) atoms. 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 La(1) atoms. In the third Mg site, Mg(3) is bonded to two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), two equivalent La(1), and two equivalent Mo(1) atoms to form a mixture of distorted edge, corner, and face-sharing MgLa2Mg8Mo2 cuboctahedra. In the fourth Mg site, Mg(4) is bonded in a 2-coordinate geometry to two equivalent Mg(2), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Mo(1) atoms. La(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Mg(2), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Mo(1) atoms. Mo(1) is bonded in a 12-coordinate geometry to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent La(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
