Hf Hf Tl Rh
(Hf)2RhTl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Hf cluster and one RhTl cluster. In the Hf cluster, there are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a single-bond geometry to one Hf(2) atom. The Hf(1)-Hf(2) bond length is 0.52 Å. In the second Hf site, Hf(2) is bonded in a single-bond geometry to one Hf(1) atom. In the RhTl cluster, Rh(1) is bonded in a single-bond geometry to one Tl(1) atom. The Rh(1)-Tl(1) bond length is 0.06 Å. Tl(1) is bonded in a single-bond geometry to one Rh(1) atom.
