Materials Data on Hf2NiP by Materials Project
Hf2NiP is delta Molybdenum Boride-derived structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Hf sites. In the first Hf site, Hf is bonded in a 7-coordinate geometry to four equivalent Ni and three equivalent P atoms. There are a spread of Hf–Ni bond distances ranging from 2.66–2.82 Å. There are two shorter (2.70 Å) and one longer (2.86 Å) Hf–P bond lengths. In the second Hf site, Hf is bonded in a 7-coordinate geometry to three equivalent Ni and four equivalent P atoms. There are two shorter (2.70 Å) and one longer (2.87 Å) Hf–Ni bond lengths. There are a spread of Hf–P bond distances ranging from 2.68–2.81 Å. Ni is bonded in a 9-coordinate geometry to seven Hf and two equivalent P atoms. Both Ni–P bond lengths are 2.31 Å. P is bonded in a 9-coordinate geometry to seven Hf and two equivalent Ni atoms.
