V V Zn As
V2ZnAs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two V2ZnAs clusters. There are two inequivalent V sites. In the first V site, V(1) is bonded in a single-bond geometry to one Zn(1) atom. The V(1)-Zn(1) bond length is 0.73 Å. In the second V site, V(2) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one As(1) atom. The V(2)-Zn(1) bond length is 1.33 Å. The V(2)-As(1) bond length is 1.88 Å. Zn(1) is bonded in a 2-coordinate geometry to one V(1) and one V(2) atom. As(1) is bonded in a single-bond geometry to one V(2) atom.
