Zr Tl Ge
ZrTlGe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ZrTlGe clusters. Zr(1) is bonded in a single-bond geometry to one Ge(1) atom. The Zr(1)-Ge(1) bond length is 0.07 Å. Tl(1) is bonded in a single-bond geometry to one Ge(1) atom. The Tl(1)-Ge(1) bond length is 2.21 Å. Ge(1) is bonded in a single-bond geometry to one Zr(1) and one Tl(1) atom.
