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 Tl2HgI4 compound; a=6.875 A, c=13.110 A for the PbHgI4 compound; a=6.40 A, c=13.12 A for the Au2HgI4 compound. The wet synthesis method is described for the CdHgI4 compounds.
