Cr3N4 crystallizes in the hexagonal P6_3/m space group. Cr(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing CrN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to three equivalent Cr(1) atoms. In the second N site, N(1) is bonded in a trigonal planar geometry to three equivalent Cr(1) atoms.
Cr3N4 crystallizes in the hexagonal P6_3/m space group. Cr(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing CrN4 tetrahedra. The Cr(1)-N(1) bond length is 1.84 Å. There is one shorter (1.82 Å) and two longer (1.86 Å) Cr(1)-N(2) bond lengths. There are two inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to three equivalent Cr(1) atoms. In the second N site, N(1) is bonded in a trigonal planar geometry to three equivalent Cr(1) atoms.
