CrN2 is Low Tridymite-like structured and crystallizes in the orthorhombic Pbcn space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to two equivalent 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(2), one N(3), and two equivalent N(1) atoms to form corner-sharing CrN4 tetrahedra. There are three inequivalent N sites. In the first N site, N(1) is bonded in a bent 150 degrees geometry to two equivalent Cr(2) atoms. In the second N site, N(2) is bonded in a bent 150 degrees 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 one Cr(1) and one Cr(2) atom.

In the first Cr site, Cr(1) is bonded to two equivalent N(2) and two equivalent N(3) atoms to form corner-sharing CrN4 tetrahedra. Both Cr(1)-N(2) bond lengths are 1.71 Å. Both Cr(1)-N(3) bond lengths are 1.76 Å. In the second Cr site, Cr(2) is bonded to one N(2), one N(3), and two equivalent N(1) atoms to form corner-sharing CrN4 tetrahedra. The Cr(2)-N(2) bond length is 1.76 Å. The Cr(2)-N(3) bond length is 1.72 Å. Both Cr(2)-N(1) bond lengths are 1.73 Å. There are three inequivalent N sites. In the first N site, N(1) is bonded in a bent 150 degrees geometry to two equivalent Cr(2) atoms. In the second N site, N(2) is bonded in a bent 150 degrees 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 one Cr(1) and one Cr(2) atom.
