The crystal structure described by TlCrSe2 crystallizes in the trigonal R-3m space group. Cr(1) is bonded to six equivalent Se(1) atoms to form edge-sharing CrSe6 octahedra. Tl(1) is bonded in a linear geometry to two equivalent Se(1) atoms. Se(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Cr(1) and one Tl(1) atom. is represented by the CIF card [CIF]
