CrN2 is quartz (beta)-like structured and crystallizes in the trigonal R-3m space group. Cr(1) is bonded to one N(1), one N(2), one N(3), and one N(4) atom to form corner-sharing CrN4 tetrahedra. There are four inequivalent N sites. In the first N site, N(1) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) atoms. In the second N site, N(2) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) atoms. In the third N site, N(3) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) atoms. In the fourth N site, N(4) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) atoms.
