CrN2 is Low Tridymite-like structured and crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one N(1), one N(2), and two equivalent N(3) atoms to form corner-sharing CrN4 tetrahedra. In the second Cr site, Cr(2) is bonded to one N(1), one N(2), and two equivalent N(4) atoms 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 one Cr(1) and one Cr(2) atom. In the second N site, N(2) is bonded in a linear geometry to one Cr(1) and one Cr(2) atom. 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(2) atoms.

In the first Cr site, Cr(1) is bonded to one N(1), one N(2), and two equivalent N(3) atoms to form corner-sharing CrN4 tetrahedra. The Cr(1)-N(1) bond length is 1.72 Å. The Cr(1)-N(2) bond length is 1.74 Å. There is one shorter (1.73 Å) and one longer (1.74 Å) Cr(1)-N(3) bond length. In the second Cr site, Cr(2) is bonded to one N(1), one N(2), and two equivalent N(4) atoms to form corner-sharing CrN4 tetrahedra. The Cr(2)-N(1) bond length is 1.75 Å. The Cr(2)-N(2) bond length is 1.72 Å. There is one shorter (1.72 Å) and one longer (1.75 Å) Cr(2)-N(4) bond length. There are four inequivalent N sites.
