| Izvleček: | Title screen Re2S7 samples have been synthesized by thiosulfate, sulfide. and thioacetamide processes and shown to differ very little in composition. Their composition has been determined by chemical analysis, IR spectroscopy, and X-ray photoelectron spectroscopy (XPS). According to chemical analysis data, the samples contain an excess of sulfur compared to the stoichiometric composition Re2S7. According to IR spectroscopy results, the synthesized Re2S7 samples contain water, hydrogen sulfate ions, and thioperrhenate ions. XPS results demonstrate the presence of sulfide, disulfide, and sulfate ions on the surface of Re2S7. In addition, the rhenium in the synthesized samples is in an odd oxidation state. Possible causes of distinctions between the structural models of Re2S7 proposed in the literature are discussed Текстовый файл AM_Agreement |
