CrN2 is beta Tridymite structured and crystallizes in the orthorhombic Ama2 space group. Cr(1) is bonded to one N(1), one N(2), and two equivalent N(3) atoms to form corner-sharing CrN4 tetrahedra. There are three inequivalent N sites. In the first N site, N(1) is bonded in a linear geometry to two equivalent Cr(1) atoms. In the second N site, N(2) is bonded in a linear geometry to two equivalent Cr(1) atoms. In the third N site, N(3) is bonded in a linear geometry to two equivalent Cr(1) atoms.

The Cr(1)-N(1) bond length is 1.72 Å. The Cr(1)-N(2) bond length is 1.73 Å. There is one shorter (1.72 Å) and one longer (1.74 Å) Cr(1)-N(3) bond length. There are three inequivalent N sites. In the first N site, N(1) is bonded in a linear geometry to two equivalent Cr(1) atoms. In the second N site, N(2) is bonded in a linear geometry to two equivalent Cr(1) atoms. In the third N site, N(3) is bonded in a linear geometry to two equivalent Cr(1) atoms.
