CrN2 is High (Orthorhombic) Tridymite structured and crystallizes in the monoclinic P2_1 space group. There are two inequivalent Cr sites. In the first Cr site, 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. In the second Cr site, Cr(2) 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 linear 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 linear geometry to one Cr(1) and one Cr(2) atom. In the fourth N site, N(4) is bonded in a linear geometry to one Cr(1) and one Cr(2) atom.
