Cr2Ni3N4 crystallizes in the monoclinic C2/c space group. Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing CrN4 tetrahedra. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a rectangular see-saw-like geometry to two equivalent N(1) and two equivalent N(2) atoms. In the second Ni site, Ni(2) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 5-coordinate geometry to two equivalent Cr(1), one Ni(2), and two equivalent Ni(1) atoms. In the second N site, N(2) is bonded in a 5-coordinate geometry to two equivalent Cr(1), one Ni(2), and two equivalent Ni(1) atoms.
