Sc Zn Zn Sb
ScZn2Sb is alpha Niobium phosphide-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ScZn2Sb cluster. Sc(1) is bonded in a distorted single-bond geometry to one Zn(2) atom. The Sc(1)-Zn(2) bond length is 1.48 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a single-bond geometry to one Zn(2) and one Sb(1) atom. The Zn(1)-Zn(2) bond length is 1.45 Å. The Zn(1)-Sb(1) bond length is 0.40 Å. In the second Zn site, Zn(2) is bonded in a 2-coordinate geometry to one Sc(1) and one Zn(1) atom. Sb(1) is bonded in a single-bond geometry to one Zn(1) atom.
