The compound can be prepared from the higher oxide:[5][6]
Also, the compound can be prepared by the reaction between both elements in a sealed tube at 450 °C, by the reaction between such components as Tc2(O2CCH3)5 and H2S-gas in a flowing system at 450 °C, and by the reaction between K2TcCl6 and H2S-gas in sulfuric acid.[7]
Technetium disulfide is isomorphous with rhenium disulfide and has an MoS2-type structure.[8]
Technetium disulphide is reduced to the metal if heated to 1000 °C in a hydrogen atmosphere.
