Hf3P crystallizes in the tetragonal P4_2/n space group. There are three inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a distorted bent 150 degrees geometry to two equivalent P(1) atoms. In the second Hf site, Hf(2) is bonded in a distorted see-saw-like geometry to four equivalent P(1) atoms. In the third Hf site, Hf(3) is bonded in a 3-coordinate geometry to three equivalent P(1) atoms. P(1) is bonded in a 9-coordinate geometry to two equivalent Hf(1), three equivalent Hf(3), and four equivalent Hf(2) atoms.
Hf3P crystallizes in the tetragonal P4_2/n space group. There are three inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a distorted bent 150 degrees geometry to two equivalent P(1) atoms. There is one shorter (2.68 Å) and one longer (2.75 Å) Hf(1)-P(1) bond length. In the second Hf site, Hf(2) is bonded in a distorted see-saw-like geometry to four equivalent P(1) atoms. There are a spread of Hf(2)-P(1) bond distances ranging from 2.71-2.78 Å. In the third Hf site, Hf(3) is bonded in a 3-coordinate geometry to three equivalent P(1) atoms. There are a spread of Hf(3)-P(1) bond distances ranging from 2.66-2.82 Å. P(1) is bonded in a 9-coordinate geometry to two equivalent Hf(1), three equivalent Hf(3), and four equivalent Hf(2) atoms.
