Materials Data on W2N by Materials Project
W2N crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of three W2N sheets oriented in the (0, 0, 1) direction. there are two inequivalent W sites. In the first W site, W is bonded in a 3-coordinate geometry to three equivalent N atoms. All W–N bond lengths are 2.10 Å. In the second W site, W is bonded in a single-bond geometry to one N atom. The W–N bond length is 1.97 Å. N is bonded in a rectangular see-saw-like geometry to four W atoms.
