Materials Data on W3N4 by Materials Project
W3N4 crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. W4+ is bonded to six N3- atoms to form a mixture of corner and edge-sharing WN6 octahedra. The corner-sharing octahedral tilt angles are 0°. All W–N bond lengths are 2.11 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded to six equivalent W4+ atoms to form corner-sharing NW6 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second N3- site, N3- is bonded in a square co-planar geometry to four equivalent W4+ atoms.
