Hf Tl Cd Cd
HfCd2Tl is alpha Po structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one HfCd2Tl cluster. Hf(1) is bonded in a distorted single-bond geometry to one Cd(1), one Cd(2), and one Tl(1) atom. The Hf(1)-Cd(1) bond length is 1.76 Å. The Hf(1)-Cd(2) bond length is 1.65 Å. The Hf(1)-Tl(1) bond length is 1.14 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 3-coordinate geometry to one Hf(1), one Cd(2), and one Tl(1) atom. The Cd(1)-Cd(2) bond length is 1.14 Å. The Cd(1)-Tl(1) bond length is 1.65 Å. In the second Cd site, Cd(2) is bonded in a 2-coordinate geometry to one Hf(1) and one Cd(1) atom. Tl(1) is bonded in a distorted single-bond geometry to one Hf(1) and one Cd(1) atom.
