Hf Be Be Tc
(Be)2HfTc is alpha oxygen-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Be clusters and two HfTc clusters. In each Be cluster, Be(1) is bonded in a single-bond geometry to one Be(1) atom. The Be(1)-Be(1) bond length is 0.14 Å. In each HfTc cluster, Hf(1) is bonded in a single-bond geometry to one Tc(1) atom. The Hf(1)-Tc(1) bond length is 0.14 Å. Tc(1) is bonded in a single-bond geometry to one Hf(1) atom.
