Abstract:  The solubility diagrams in the CdSeO₃ —SeO₂ —H₂O and HgSeO₃ —SeO₂ —H₂O systems at 298 К were studied for the first time. Two mo­difications of CdSeO₃ , cadmium(II) diselenite CdSe 2 0 5 and cadmium(II) dihydrogen-tetrakis(selenite) Cd₃H₂ (SeO₃)₄ and mercury(II) dihydrogen-tetrakis(selenite) Hg₃H₂(SeO₃)₄ were prepared. The thermal stability and infrared molecular spectra of these compounds were studied and used to determine the force constants of the selenium—oxygen bonds and to characterize the hydrogen bonds present. Modifications of cadmium(II) selenite were studied by X-ray powder analysis.
