MgLuTl crystallizes in the hexagonal P-62m space group. Mg(1) is bonded to two equivalent Tl(1) and two equivalent Tl(2) atoms to form a mixture of distorted corner and edge-sharing MgTl4 tetrahedra. Lu(1) is bonded in a 5-coordinate geometry to one Tl(2) and four equivalent Tl(1) atoms. There are two inequivalent Tl sites. In the first Tl site, Tl(2) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent Lu(1) atoms. In the second Tl site, Tl(1) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent Lu(1) atoms.
MgLuTl crystallizes in the hexagonal P-62m space group. Mg(1) is bonded to two equivalent Tl(1) and two equivalent Tl(2) atoms to form a mixture of distorted corner and edge-sharing MgTl4 tetrahedra. Both Mg(1)-Tl(1) bond lengths are 2.86 Å. Both Mg(1)-Tl(2) bond lengths are 2.90 Å. Lu(1) is bonded in a 5-coordinate geometry to one Tl(2) and four equivalent Tl(1) atoms. The Lu(1)-Tl(2) bond length is 3.19 Å. All Lu(1)-Tl(1) bond lengths are 3.16 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(2) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent Lu(1) atoms. In the second Tl site, Tl(1) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent Lu(1) atoms.
