ZnTl is Cyanogen Chloride-derived structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two ZnTl clusters. Zn(1) is bonded in a linear geometry to one Zn(1) and one Tl(1) atom. The Zn(1)-Zn(1) bond length is 0.24 Å. The Zn(1)-Tl(1) bond length is 0.98 Å. Tl(1) is bonded in a single-bond geometry to one Zn(1) atom.
