Al Al Zn Fe
FeZnAl2 crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one FeZnAl2 cluster. Fe(1) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one Al(1) atom. The Fe(1)-Zn(1) bond length is 0.95 Å. The Fe(1)-Al(1) bond length is 0.28 Å. Zn(1) is bonded in a linear geometry to one Fe(1) and one Al(2) atom. The Zn(1)-Al(2) bond length is 1.21 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a single-bond geometry to one Fe(1) atom. In the second Al site, Al(2) is bonded in a single-bond geometry to one Zn(1) atom.
