Technetium disulfide was prepared by reaction between the elements in a sealed tube at 450 °C, by reaction between Tc 2 (O 2 CCH 3 ) 5 and H 2 S gas in a flowing system at 450 °C and by reaction between K 2 TcCl 6 and H 2 S gas in sulfuric acid. The samples were analysed by X-ray absorption fine structure (XAFS) spectroscopy.
