X-RAY STUDIES ON Tl<sub>2</sub>HgI<sub>4</sub>, PbHgI<sub>4</sub>, CdHgI<sub>4</sub> AND Au<sub>2</sub>HgI<sub>4</sub> INORGANIC COMBINATIONS
Abstract:
<p align="justify"> The parameters of the crystalline elementary cells were calculated starting from the diffraction X-ray spectra obtained on microcrystalline powders of compounds with thermocbromic and semiconductor properties. The respective cell units belong to the tetragonal system and have the following values: a=6.450 A, c=1.14 A for the Tl<sub>2</sub>HgI<sub>4</sub> compound; a=6.875 A, c=13.110 A for the PbHgI<sub>4</sub> compound; a=6.40 A, c=13.12 A for the Au<sub>2</sub>HgI<sub>4</sub> compound. The wet synthesis method is described for the CdHgI<sub>4</sub> compounds. </p>
