Hf In Ge Ge
HfInGe2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfInGe2 clusters. Hf(1) is bonded in a distorted single-bond geometry to one In(1) and one Ge(2) atom. The Hf(1)-In(1) bond length is 0.29 Å. The Hf(1)-Ge(2) bond length is 2.06 Å. In(1) is bonded in a distorted single-bond geometry to one Hf(1) and one Ge(1) atom. The In(1)-Ge(1) bond length is 1.79 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a distorted single-bond geometry to one In(1) atom. In the second Ge site, Ge(2) is bonded in a distorted single-bond geometry to one Hf(1) atom.
