Hf Hf Cd Tc
Hf2TcCd crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Hf2TcCd cluster. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a distorted L-shaped geometry to one Hf(2), one Tc(1), and one Cd(1) atom. The Hf(1)-Hf(2) bond length is 1.37 Å. The Hf(1)-Tc(1) bond length is 1.23 Å. The Hf(1)-Cd(1) bond length is 1.09 Å. In the second Hf site, Hf(2) is bonded in a 3-coordinate geometry to one Hf(1), one Tc(1), and one Cd(1) atom. The Hf(2)-Tc(1) bond length is 1.37 Å. The Hf(2)-Cd(1) bond length is 1.57 Å. Tc(1) is bonded in a 2-coordinate geometry to one Hf(1) and one Hf(2) atom. Cd(1) is bonded in a distorted single-bond geometry to one Hf(1) and one Hf(2) atom.
