Mg6CdB crystallizes in the orthorhombic Amm2 space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 2-coordinate geometry to two equivalent Mg(2), two equivalent Mg(4), two equivalent Cd(1), and two equivalent B(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 Cd(1) atoms. In the third Mg site, Mg(3) is bonded in a 1-coordinate geometry to two equivalent Mg(2), two equivalent Mg(4), two equivalent Cd(1), and one B(1) atom. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms. Cd(1) is bonded in a distorted q6 geometry to two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms. B(1) is bonded in a distorted hexagonal planar geometry to two equivalent Mg(3) and four equivalent Mg(1) atoms.
