On the Knowledge of 2 Thallium-Tellurochromites (Tlcrte2 and Tlcr5Te8)
The title compounds were prepared and their crystal structures determined. TlCrTe2 is hexagonal (a = 4.016 Angstrom, c = 7.927 Angstrom) having 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) revealed a disorder of thallium in a split position within the channels of the [Cr5Te8] framework.
