The material structure described by TlCr5Te8 crystallizes in the triclinic P1 space group. The structure consists of one 7440-28-0 atom inside a Cr5Te8 framework. In the Cr5Te8 framework, there are five inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one Te(1), one Te(2), two equivalent Te(5), and two equivalent Te(7) atoms to form a mixture of corner, edge, and face-sharing CrTe6 octahedra. The corner-sharing octahedral tilt angles range from 48-53°. In the second Cr site, Cr(2) is bonded to one Te(1), one Te(3), two equivalent Te(6), and two equivalent Te(7) atoms to form a mixture of corner, edge, and face-sharing CrTe6 octahedra. The corner-sharing octahedral tilt angles range from 48-53°. In the third Cr site, Cr(3) is bonded to one Te(4), one Te(5), two equivalent Te(1), and two equivalent Te(8) atoms to form a mixture of corner and edge-sharing CrTe6 octahedra. The corner-sharing octahedral tilt angles range from 52-53°. In the fourth Cr site, Cr(4) is bonded to one Te(6), one Te(8), two equivalent Te(2), and two equivalent Te(3) atoms to form a mixture of corner, edge, and face-sharing CrTe6 octahedra. The corner-sharing octahedral tilt angles range from 48-53°. In the fifth Cr site, Cr(5) is bonded to one Te(7), one Te(8), two equivalent Te(2), and two equivalent Te(4) atoms to form a mixture of corner, edge, and face-sharing CrTe6 octahedra. The corner-sharing octahedral tilt angles range from 48-53°. There are eight inequivalent Te sites. In the first Te site, Te(1) is bonded in a rectangular see-saw-like geometry to one Cr(1), one Cr(2), and two equivalent Cr(3) atoms. In the second Te site, Te(2) is bonded to one Cr(1), two equivalent Cr(4), and two equivalent Cr(5) atoms to form distorted edge-sharing TeCr5 square pyramids. In the third Te site, Te(3) is bonded in a distorted T-shaped geometry to one Cr(2) and two equivalent Cr(4) atoms. In the fourth Te site, Te(4) is bonded in a 3-coordinate geometry to one Cr(3) and two equivalent Cr(5) atoms. In the fifth Te site, Te(5) is bonded in a distorted T-shaped geometry to one Cr(3) and two equivalent Cr(1) atoms. In the sixth Te site, Te(6) is bonded in a distorted T-shaped geometry to one Cr(4) and two equivalent Cr(2) atoms. In the seventh Te site, Te(7) is bonded to one Cr(5), two equivalent Cr(1), and two equivalent Cr(2) atoms to form distorted edge-sharing TeCr5 square pyramids. In the eighth Te site, Te(8) is bonded in a rectangular see-saw-like geometry to one Cr(4), one Cr(5), and two equivalent Cr(3) atoms. is represented by the CIF card [CIF]
