CrBi2N3 crystallizes in the monoclinic C2/c space group. 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. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a distorted T-shaped geometry to one N(2) and two equivalent N(3) atoms. In the second Bi site, Bi(2) is bonded in a 3-coordinate geometry to one N(1), one N(2), and one N(3) atom. There are four inequivalent N sites. In the first N site, N(4) is bonded in a linear geometry to two equivalent Cr(1) atoms. In the second N site, N(1) is bonded in a bent 150 degrees geometry to two equivalent Cr(1) and two equivalent Bi(2) atoms. In the third N site, N(2) is bonded in a distorted trigonal planar geometry to one Cr(1), one Bi(1), and one Bi(2) atom. In the fourth N site, N(3) is bonded to one Cr(1), one Bi(2), and two equivalent Bi(1) atoms to form distorted edge-sharing NCrBi3 tetrahedra.
