The material described by BaMg6Cd crystallizes in the orthorhombic Amm2 space group. Ba(1) is bonded to two equivalent Mg(3), four equivalent Mg(1), four equivalent Mg(2), and two equivalent Cd(1) atoms to form a mixture of face and corner-sharing BaMg10Cd2 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to two equivalent Ba(1), one Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and one Cd(1) atom. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to two equivalent Ba(1), one Mg(3), two equivalent Mg(1), and two equivalent Cd(1) atoms. In the third Mg site, Mg(3) is bonded in a 10-coordinate geometry to two equivalent Ba(1), two equivalent Mg(2), two equivalent Mg(4), and four equivalent Mg(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 2-coordinate geometry to two equivalent Mg(3), four equivalent Mg(1), and two equivalent Cd(1) atoms. Cd(1) is bonded in a 10-coordinate geometry to two equivalent Ba(1), two equivalent Mg(1), two equivalent Mg(4), and four equivalent Mg(2) atoms. is represented by the CIF file [CIF]
