Title: Materials Data on Hf3N4 by Materials Project

Abstract

Hf3N4 is Hausmannite structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. there are two inequivalent Hf4+ sites. In the first Hf4+ site, Hf4+ is bonded to six equivalent N3- atoms to form HfN6 octahedra that share corners with six equivalent HfN4 tetrahedra and edges with six equivalent HfN6 octahedra. All Hf–N bond lengths are 2.20 Å. In the second Hf4+ site, Hf4+ is bonded to four equivalent N3- atoms to form corner-sharing HfN4 tetrahedra. The corner-sharing octahedral tilt angles are 57°. All Hf–N bond lengths are 2.09 Å. N3- is bonded in a distorted rectangular see-saw-like geometry to four Hf4+ atoms.
