The compound described by Mg6SnSb crystallizes in the orthorhombic Amm2 space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 3-coordinate geometry to two equivalent Sn(1) and two equivalent Sb(1) atoms. In the second Mg site, Mg(2) is bonded in a distorted linear geometry to two equivalent Sn(1) atoms. In the third Mg site, Mg(3) is bonded in a 3-coordinate geometry to two equivalent Sn(1) and one Sb(1) atom. In the fourth Mg site, Mg(4) is bonded in a distorted linear geometry to two equivalent Sb(1) atoms. Sn(1) is bonded in a 10-coordinate geometry to two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms. Sb(1) is bonded in a 8-coordinate geometry to two equivalent Mg(3), two equivalent Mg(4), and four equivalent Mg(1) atoms. is represented by the CIF card [CIF]
