Hf Hf Hf Tl Tl Tl
HfTl crystallizes in the triclinic P1 space group. The structure is one-dimensional and consists of three HfTl clusters. Hf(1) is bonded in a distorted single-bond geometry to one Tl(1) atom. The Hf(1)-Tl(1) bond length is 1.60 Å. Tl(1) is bonded in a distorted single-bond geometry to one Hf(1) atom.
