MgAgSb crystallizes in the tetragonal I-4c2 space group. Mg(1) is bonded in a 8-coordinate geometry to one Ag(1), one Ag(2), two equivalent Ag(3), and four equivalent Sb(1) atoms. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Mg(1), two equivalent Ag(2), two equivalent Ag(3), and four equivalent Sb(1) atoms to form distorted corner-sharing AgMg4Ag4Sb4 cuboctahedra. In the second Ag site, Ag(2) is bonded in a 8-coordinate geometry to four equivalent Mg(1), two equivalent Ag(1), and four equivalent Sb(1) atoms. In the third Ag site, Ag(3) is bonded in a 9-coordinate geometry to four equivalent Mg(1), one Ag(1), and four equivalent Sb(1) atoms. Sb(1) is bonded in a 8-coordinate geometry to four equivalent Mg(1), one Ag(1), one Ag(2), and two equivalent Ag(3) atoms.
MgAgSb crystallizes in the tetragonal I-4c2 space group. Mg(1) is bonded in a 8-coordinate geometry to one Ag(1), one Ag(2), two equivalent Ag(3), and four equivalent Sb(1) atoms. The Mg(1)-Ag(1) bond length is 3.24 Å. The Mg(1)-Ag(2) bond length is 2.98 Å. There is one shorter (2.99 Å) and one longer (3.01 Å) Mg(1)-Ag(3) bond length. There are a spread of Mg(1)-Sb(1) bond distances ranging from 2.96-3.24 Å. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Mg(1), two equivalent Ag(2), two equivalent Ag(3), and four equivalent Sb(1) atoms to form distorted corner-sharing AgMg4Ag4Sb4 cuboctahedra. Both Ag(1)-Ag(2) bond lengths are 3.24 Å. Both Ag(1)-Ag(3) bond lengths are 2.88 Å. All Ag(1)-Sb(1) bond lengths are 3.01 Å.
