Zn Cu Sb Sb
CuZnSb2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CuZnSb2 cluster. Cu(1) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one Sb(2) atom. The Cu(1)-Zn(1) bond length is 1.48 Å. The Cu(1)-Sb(2) bond length is 0.87 Å. Zn(1) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one Sb(1) atom. The Zn(1)-Sb(1) bond length is 1.33 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted single-bond geometry to one Zn(1) atom. In the second Sb site, Sb(2) is bonded in a distorted single-bond geometry to one Cu(1) atom.
