Materials Data on HfGeOs by Materials Project
HfOsGe crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Hf is bonded in a 11-coordinate geometry to six equivalent Os and five Ge atoms. There are two shorter (2.96 Å) and four longer (3.10 Å) Hf–Os bond lengths. There are four shorter (2.78 Å) and one longer (2.81 Å) Hf–Ge bond lengths. Os is bonded in a 12-coordinate geometry to six equivalent Hf, two equivalent Os, and four Ge atoms. Both Os–Os bond lengths are 2.87 Å. There are two shorter (2.53 Å) and two longer (2.59 Å) Os–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six equivalent Hf and three equivalent Os atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to three equivalent Hf and six equivalent Os atoms.
