The title compounds were prepared and their crystal structures determi
ned. TlCrTe2 is hexagonal (a = 4.016 Angstrom, c = 7.927 Angstrom) hav
ing a CdI2 derived pseudo-intercalation structure. The single crystal
refinement of TlCr5Te8 (monoclinic TlV5S8 type, a = 20.241 Angstrom, b
= 3.9141 Angstrom, c = 9.481 Angstrom, beta = 104.65 degrees) reveale
d a disorder of thallium in a split position within the channels of th
e [Cr5Te8] framework.
