The structure described by TlSbSe2 crystallizes in the orthorhombic Cmmm space group. Tl(1) is bonded to four equivalent Sb(1) and two equivalent Se(1) atoms to form a mixture of corner and edge-sharing TlSb4Se2 octahedra. The corner-sharing octahedra are not tilted. Sb(1) is bonded in a square co-planar geometry to four equivalent Tl(1) atoms. Se(1) is bonded in a trigonal planar geometry to one Tl(1) and two equivalent Se(1) atoms. is represented by the CIF card [CIF]
