Hf Hf Sc Sb
(Hf)2ScSb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Hf clusters and two ScSb clusters. In each Hf cluster, Hf(1) is bonded in a 1-coordinate geometry to one Hf(1) atom. The Hf(1)-Hf(1) bond length is 0.81 Å. In each ScSb cluster, Sc(1) is bonded in a single-bond geometry to one Sb(1) atom. The Sc(1)-Sb(1) bond length is 0.81 Å. Sb(1) is bonded in a single-bond geometry to one Sc(1) atom.
