Tl V Zn Zn
VZn2Tl crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one VZn2Tl cluster. V(1) is bonded in a distorted linear geometry to one Zn(1) and one Zn(2) atom. The V(1)-Zn(1) bond length is 1.86 Å. The V(1)-Zn(2) bond length is 1.31 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a single-bond geometry to one V(1) and one Tl(1) atom. The Zn(1)-Tl(1) bond length is 0.33 Å. In the second Zn site, Zn(2) is bonded in a single-bond geometry to one V(1) atom. Tl(1) is bonded in a single-bond geometry to one Zn(1) atom.
