Materials Data on HfMoP by Materials Project

HfMoP crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Hf is bonded in a 11-coordinate geometry to six equivalent Mo and five P atoms. There are two shorter (2.93 Å) and four longer (2.98 Å) Hf–Mo bond lengths. There are four shorter (2.71 Å) and one longer (2.80 Å) Hf–P bond lengths. Mo is bonded in a 10-coordinate geometry to six equivalent Hf and four P atoms. There are two shorter (2.45 Å) and two longer (2.63 Å) Mo–P bond lengths. There are two inequivalent P sites. In the first P site, P is bonded in a 9-coordinate geometry to three equivalent Hf and six equivalent Mo atoms. In the second P site, P is bonded in a 9-coordinate geometry to six equivalent Hf and three equivalent Mo atoms.

Materials Data on Hf9Mo4P by Materials Project

Hf9Mo4P crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Hf sites. In the first Hf site, Hf is bonded in a 1-coordinate geometry to four Mo and one P atom. There are a spread of Hf–Mo bond distances ranging from 2.88–3.11 Å. The Hf–P bond length is 2.68 Å. In the second Hf site, Hf is bonded in a distorted T-shaped geometry to two equivalent Mo and one P atom. Both Hf–Mo bond lengths are 2.90 Å. The Hf–P bond length is 3.08 Å. There are two inequivalent Mo sites. In the first Mo site, Mo is bonded in a 12-coordinate geometry to eight Hf and four Mo atoms. There are two shorter (2.72 Å) and two longer (2.87 Å) Mo–Mo bond lengths. In the second Mo site, Mo is bonded to six equivalent Hf and six equivalent Mo atoms to form face-sharing MoHf6Mo6 cuboctahedra. P is bonded in a 9-coordinate geometry to nine Hf atoms.
