MgSmIn crystallizes in the hexagonal P-62m space group. Mg(1) is bonded to two equivalent In(1) and two equivalent In(2) atoms to form a mixture of distorted corner and edge-sharing MgIn4 tetrahedra. Sm(1) is bonded in a 5-coordinate geometry to one In(2) and four equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent Sm(1) atoms. In the second In site, In(2) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent Sm(1) atoms.
MgSmIn crystallizes in the hexagonal P-62m space group. Mg(1) is bonded to two equivalent In(1) and two equivalent In(2) atoms to form a mixture of distorted corner and edge-sharing MgIn4 tetrahedra. Both Mg(1)-In(1) bond lengths are 2.96 Å. Both Mg(1)-In(2) bond lengths are 2.99 Å. Sm(1) is bonded in a 5-coordinate geometry to one In(2) and four equivalent In(1) atoms. The Sm(1)-In(2) bond length is 3.29 Å. All Sm(1)-In(1) bond lengths are 3.27 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent Sm(1) atoms. In the second In site, In(2) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent Sm(1) atoms.
