ZnCdSb2 crystallizes in the orthorhombic P2_12_12_1 space group. Cd(1) is bonded in a 5-coordinate geometry to one Zn(1), one Sb(2), and three equivalent Sb(1) atoms. Zn(1) is bonded in a 5-coordinate geometry to one Cd(1), one Sb(1), and three equivalent Sb(2) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 5-coordinate geometry to three equivalent Cd(1), one Zn(1), and one Sb(2) atom. In the second Sb site, Sb(2) is bonded in a 5-coordinate geometry to one Cd(1), three equivalent Zn(1), and one Sb(1) atom.
