CrMn3Te4 crystallizes in the trigonal P-3m1 space group. Cr(1) is bonded to two equivalent Mn(2) and six equivalent Te(1) atoms to form distorted CrMn2Te6 octahedra that share corners with twelve equivalent Mn(2)CrTe6 octahedra, edges with six equivalent Cr(1)Mn2Te6 octahedra, and faces with two equivalent Mn(2)CrTe6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to six equivalent Te(2) atoms to form distorted MnTe6 octahedra that share corners with twelve equivalent Mn(2)CrTe6 octahedra, edges with six equivalent Mn(1)Te6 octahedra, and faces with two equivalent Mn(2)CrTe6 octahedra. The corner-sharing octahedral tilt angles are 51°. In the second Mn site, Mn(2) is bonded to one Cr(1), three equivalent Te(1), and three equivalent Te(2) atoms to form distorted MnCrTe6 octahedra that share  a cornercorner with one Mn(2)CrTe6 octahedra, corners with six equivalent Cr(1)Mn2Te6 octahedra, corners with six equivalent Mn(1)Te6 octahedra, edges with six equivalent Mn(2)CrTe6 octahedra,  a faceface with one Cr(1)Mn2Te6 octahedra, and  a faceface with one Mn(1)Te6 octahedra. The corner-sharing octahedral tilt angles range from 0-51°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to three equivalent Cr(1) and three equivalent Mn(2) atoms. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to three equivalent Mn(1) and three equivalent Mn(2) atoms.
