Materials Data on Hf3P by Materials Project

Hf3P crystallizes in the tetragonal P4_2/n space group. The structure is three-dimensional. there are three inequivalent Hf sites. In the first Hf site, Hf is bonded in a distorted bent 150 degrees geometry to two equivalent P atoms. There are one shorter (2.70 Å) and one longer (2.76 Å) Hf–P bond lengths. In the second Hf site, Hf is bonded in a distorted see-saw-like geometry to four equivalent P atoms. There are a spread of Hf–P bond distances ranging from 2.72–2.80 Å. In the third Hf site, Hf is bonded in a 3-coordinate geometry to three equivalent P atoms. There are a spread of Hf–P bond distances ranging from 2.67–2.82 Å. P is bonded in a 9-coordinate geometry to nine Hf atoms.
