TlSbTe2 crystallizes in the monoclinic C2/m space group. Tl(1) is bonded in a distorted linear geometry to two equivalent Sb(1) and four equivalent Te(1) atoms. Sb(1) is bonded in a 8-coordinate geometry to two equivalent Tl(1) and six equivalent Te(1) atoms. Te(1) is bonded in a 7-coordinate geometry to two equivalent Tl(1), three equivalent Sb(1), and two equivalent Te(1) atoms.
TlSbTe2 crystallizes in the monoclinic C2/m space group. Tl(1) is bonded in a distorted linear geometry to two equivalent Sb(1) and four equivalent Te(1) atoms. Both Tl(1)-Sb(1) bond lengths are 3.45 Å. All Tl(1)-Te(1) bond lengths are 3.59 Å. Sb(1) is bonded in a 8-coordinate geometry to two equivalent Tl(1) and six equivalent Te(1) atoms. There are four shorter (3.14 Å) and two longer (3.38 Å) Sb(1)-Te(1) bond lengths. Te(1) is bonded in a 7-coordinate geometry to two equivalent Tl(1), three equivalent Sb(1), and two equivalent Te(1) atoms. Both Te(1)-Te(1) bond lengths are 3.17 Å.
