Al Zn Zn W
WZn2Al crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WZn2Al clusters. W(1) is bonded in a 3-coordinate geometry to one Zn(1), one Zn(2), and one Al(1) atom. The W(1)-Zn(1) bond length is 1.58 Å. The W(1)-Zn(2) bond length is 1.58 Å. The W(1)-Al(1) bond length is 1.60 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 1-coordinate geometry to one W(1) atom. In the second Zn site, Zn(2) is bonded in a 1-coordinate geometry to one W(1) atom. Al(1) is bonded in a distorted single-bond geometry to one W(1) atom.
