The new compounds, tetramethylammonium hydrogenselenate monohydrate ((Me4N)HSeO4 center dot H2O) and lithium tetramethylammonium selenate tetrahydrate (Li(Me4N)SeO4 center dot 4H(2)O), have been found in these systems. Both substances were characterised by chemical analysis and IR molecular spectroscopy. Both of the title substances decompose under the influence of X-radiation and, thus, their structures cannot be determined. The radiolysis of both substances was studied in greater detail. Tetramethylammonium hydrogenselenate monohydrate is dehydrated by X-radiation to form the anhydrous salt. The reaction is controlled by first-order kinetics with a rate constant of 1.30(3) x 10(-3) s(-1).
