Sc Al Al Zn
ScZnAl2 is alpha Niobium phosphide-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ScZnAl2 cluster. Sc(1) is bonded in a 2-coordinate geometry to one Zn(1) and one Al(2) atom. The Sc(1)-Zn(1) bond length is 0.72 Å. The Sc(1)-Al(2) bond length is 0.72 Å. Zn(1) is bonded in a single-bond geometry to one Sc(1), one Al(1), and one Al(2) atom. The Zn(1)-Al(1) bond length is 0.49 Å. The Zn(1)-Al(2) bond length is 0.19 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 2-coordinate geometry to one Zn(1) and one Al(2) atom. The Al(1)-Al(2) bond length is 0.49 Å. In the second Al site, Al(2) is bonded in a single-bond geometry to one Sc(1), one Zn(1), and one Al(1) atom.
