CrN2 crystallizes in the hexagonal P6_3/mmc space group. Cr(1) is bonded to one N(1), one N(3), and two equivalent N(2) atoms to form corner-sharing CrN4 tetrahedra. There are three inequivalent N sites. In the first N site, N(2) is bonded in a bent 120 degrees geometry to two equivalent Cr(1) atoms. In the second N site, N(1) is bonded in a linear geometry to two equivalent Cr(1) atoms. In the third N site, N(3) is bonded in a distorted bent 150 degrees geometry to two equivalent Cr(1) atoms.
