Hf Hf Ge Mo
Hf2MoGe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Hf2MoGe clusters. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a single-bond geometry to one Mo(1) atom. The Hf(1)-Mo(1) bond length is 1.81 Å. In the second Hf site, Hf(2) is bonded in a single-bond geometry to one Ge(1) atom. The Hf(2)-Ge(1) bond length is 0.70 Å. Mo(1) is bonded in a distorted bent 120 degrees geometry to one Hf(1) and one Ge(1) atom. The Mo(1)-Ge(1) bond length is 1.76 Å. Ge(1) is bonded in a distorted single-bond geometry to one Hf(2) and one Mo(1) atom.
