The structure described by Ti2CrN3 crystallizes in the orthorhombic Immm space group. Ti(1) is bonded in a 7-coordinate geometry to two equivalent N(1) and five equivalent N(2) atoms. Cr(1) is bonded in a square co-planar 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 to four equivalent Ti(1) and two equivalent Cr(1) atoms to form NTi4Cr2 octahedra that share corners with two equivalent N(1)Ti4Cr2 octahedra, corners with twelve equivalent N(2)Ti5Cr octahedra, edges with two equivalent N(1)Ti4Cr2 octahedra, and faces with four equivalent N(2)Ti5Cr octahedra. The corner-sharing octahedral tilt angles range from 0-63°. In the second N site, N(2) is bonded to five equivalent Ti(1) and one Cr(1) atom to form NTi5Cr octahedra that share corners with five equivalent N(2)Ti5Cr octahedra, corners with six equivalent N(1)Ti4Cr2 octahedra, edges with eight equivalent N(2)Ti5Cr octahedra, and faces with two equivalent N(1)Ti4Cr2 octahedra. The corner-sharing octahedral tilt angles range from 0-63°. is represented by the CIF file [CIF]
