Materials Data on Hf2SeN2 by Materials Project
Hf2N2Se crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Hf4+ is bonded in a 4-coordinate geometry to four equivalent N3- and three equivalent Se2- atoms. There are three shorter (2.13 Å) and one longer (2.17 Å) Hf–N bond lengths. All Hf–Se bond lengths are 2.92 Å. N3- is bonded to four equivalent Hf4+ atoms to form a mixture of distorted corner and edge-sharing NHf4 tetrahedra. Se2- is bonded in a 6-coordinate geometry to six equivalent Hf4+ atoms.
