Materials Data on HfGePd by Materials Project

HfPdGe crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are three inequivalent Hf sites. In the first Hf site, Hf is bonded in a 10-coordinate geometry to five Pd and five Ge atoms. There are a spread of Hf–Pd bond distances ranging from 3.01–3.22 Å. There are a spread of Hf–Ge bond distances ranging from 2.78–2.83 Å. In the second Hf site, Hf is bonded in a 12-coordinate geometry to seven Pd and five Ge atoms. There are a spread of Hf–Pd bond distances ranging from 2.97–3.19 Å. There are a spread of Hf–Ge bond distances ranging from 2.82–2.85 Å. In the third Hf site, Hf is bonded in a 5-coordinate geometry to six Pd and five Ge atoms. There are a spread of Hf–Pd bond distances ranging from 3.00–3.30 Å. There are a spread of Hf–Ge bond distances ranging from 2.76–2.85 Å. There are three inequivalent Pd sites. In the first Pd site, Pd is bonded in a 12-coordinate geometry to five Hf, three Pd, and four Ge atoms. There are one shorter (2.85 Å) and two longer (2.89 Å) Pd–Pd bond lengths. There are one shorter (2.52 Å) and three longer (2.62 Å) Pd–Ge bond lengths. In the second Pd site, Pd is bonded in a 12-coordinate geometry to six Hf, two equivalent Pd, and four Ge atoms. Both Pd–Pd bond lengths are 2.92 Å. There are a spread of Pd–Ge bond distances ranging from 2.54–2.67 Å. In the third Pd site, Pd is bonded in a 12-coordinate geometry to seven Hf, one Pd, and four Ge atoms. There are one shorter (2.52 Å) and three longer (2.56 Å) Pd–Ge bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four Hf and five Pd atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six Hf and three Pd atoms. In the third Ge site, Ge is bonded in a 9-coordinate geometry to five Hf and four Pd atoms.
