MgCuSn is half-Heusler structured and crystallizes in the cubic F-43m space group. Mg(1) is bonded to six equivalent Cu(1) and four equivalent Sn(1) atoms to form a mixture of distorted corner and face-sharing MgCu6Sn4 tetrahedra. Cu(1) is bonded in a distorted q6 geometry to six equivalent Mg(1) and four equivalent Sn(1) atoms. Sn(1) is bonded in a body-centered cubic geometry to four equivalent Mg(1) and four equivalent Cu(1) atoms.
