Реферат:
A series of new sulfur-de5cient polysul5des, PrS1.900 (2) , PrS1.846 (6) , PrS1.766 (8) , and PrS1.702 (7) , in addition to stoichiometric PrS2 , has been found by the detailed study of the PrS2+PrS1.5 system in the temperature range 350}10003C. The phase individuality of the polysul5des has been proved on the basis of data of a sensitive static tensimetric method with a quartz Bourdon gauge, X-ray single-crystal structure analysis, and Raman spectroscopy. The vapor pressure and evaporation thermodynamic parameters of the polysul5des have been determined. Information on a structural distortion of the (S2+2 )-polyanionic fragment in the sulfur-de5cient phases has been extracted from the Raman spectra components assigned to vibrations of this fragment.
