Abstract: The solubility diagrams of the Li₂SeO₃—H₂Se0₃—H₂0 and Tl₂Se0₃—H₂Se0₃—H₂0 systems were studied for the first time at 298 K. On the basis of the study of solubility, the conditions for the preparation of the sub­ stances were refined and the following lithium compounds were prepared:  Li₂SeO₃ • H₂0 , LiHSe0₃ , and LiH₃(Se0₃)₂ ; the prepared thallium compounds involved TlH₃(Se0₃)₂ and the compound Tl₂Se₂0₅ that has not yet been described. The thermoanalytical properties and the IR spectra were studied for all the compounds prepared. On the basis of the results obtained, hydrogen bonding in Li₂SeO₃ • H₂0 was characterized and the behaviour of protons in the hydrogen bonds in acid salts was described from the point of view of the occupation of ordered or disordered positions.
