The compound described by MgSb2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent Sb(2) and four 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 four equivalent Mg(1) atoms. In the second Sb site, Sb(2) is bonded in a 6-coordinate geometry to two equivalent Mg(1) and four equivalent Sb(2) atoms. is represented by the CIF file [CIF]
