Recent developments in the synthetic chemistry of technetium disulfide.

Technetium disulfide was prepared by reaction between the elements in a sealed tube at 450 °C, by reaction between Tc2(O2CCH3)5 and H2S gas in a flowing system at 450 °C and by reaction between K2TcCl6 and H2S gas in sulfuric acid. The samples were analysed by X-ray absorption fine structure (XAFS) spectroscopy.
