RESUMEN
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.

RESUMEN
The reaction between HTcO(4) and MeOH in 13 M H(2)SO(4) was investigated by (99)Tc NMR, UV-visible and X-ray absorption fine structure (XAFS) spectroscopy. Experimental results and first principles calculations show the formation of Tc(+5) sulfate complexes. The results expand the fundamental understanding of Tc in high acid solutions.
