MgSb2 crystallizes in the monoclinic C2/m space group. Mg(1) is bonded in a 11-coordinate geometry to two equivalent Mg(1), four equivalent Sb(2), and five equivalent Sb(1) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 4-coordinate geometry to five equivalent Mg(1) atoms. In the second Sb site, Sb(2) is bonded in a 7-coordinate geometry to four equivalent Mg(1) and three equivalent Sb(2) atoms.
MgSb2 crystallizes in the monoclinic C2/m space group. Mg(1) is bonded in a 11-coordinate geometry to two equivalent Mg(1), four equivalent Sb(2), and five equivalent Sb(1) atoms. Both Mg(1)-Mg(1) bond lengths are 3.20 Å. There are two shorter (3.13 Å) and two longer (3.37 Å) Mg(1)-Sb(2) bond lengths. There are a spread of Mg(1)-Sb(1) bond distances ranging from 3.06-3.47 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 4-coordinate geometry to five equivalent Mg(1) atoms. In the second Sb site, Sb(2) is bonded in a 7-coordinate geometry to four equivalent Mg(1) and three equivalent Sb(2) atoms. There is one shorter (3.06 Å) and two longer (3.20 Å) Sb(2)-Sb(2) bond lengths.
