Materials Data on Hf2CoP by Materials Project
Hf2CoP 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 Co and three equivalent P atoms. There are a spread of Hf–Co bond distances ranging from 2.63–2.86 Å. There are two shorter (2.73 Å) and one longer (2.80 Å) Hf–P bond lengths. In the second Hf site, Hf is bonded in a 7-coordinate geometry to three equivalent Co and four equivalent P atoms. There are two shorter (2.65 Å) and one longer (2.85 Å) Hf–Co bond lengths. There are three shorter (2.71 Å) and one longer (2.78 Å) Hf–P bond lengths. Co is bonded in a 9-coordinate geometry to seven Hf and two equivalent P atoms. Both Co–P bond lengths are 2.31 Å. P is bonded in a 9-coordinate geometry to seven Hf and two equivalent Co atoms.
