CrN2 crystallizes in the monoclinic P2 space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one N(1), one N(3), one N(4), and one N(5) 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(5) atom to form corner-sharing CrN4 tetrahedra. There are five 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 bent 150 degrees geometry to two equivalent Cr(2) atoms. In the third N site, N(3) is bonded in a water-like geometry to one Cr(1) and one Cr(2) atom. In the fourth N site, N(4) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) atoms. In the fifth N site, N(5) is bonded in a bent 150 degrees geometry to one Cr(1) and one Cr(2) atom.
