The compound described by CrN2 is High (Orthorhombic) Tridymite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing CrN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded in a linear 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. is represented by the Crystallographic Information File (CIF) [CIF]
