Rhenium(VII) sulfide is a chemical compound with the formula Re2S7. It can be produced through the reaction of ReO4- and H2S in 4N HCl.[1]

Synthesis[edit]

  • Direct combination of rhenium and sulfur:
\mathrm{2Re + 7S \ \xrightarrow{\Delta}\ Re_2S_7 }
\mathrm{Re_2O_7 + 7H_2S \ \xrightarrow{\Delta}\ Re_2S_7 + 7H_2O }

Reactions[edit]

Rhenium(VII) sulfide decomposes when heated in vacuum:

\mathrm{Re_2S_7 \ \xrightarrow{600^oC}\ 2ReS_2 + 3S }

It is converted to oxide when heated in air:

\mathrm{2Re_2S_7 + 21O_2 \ \xrightarrow{\Delta}\ 2Re_2O_7 + 14SO_2 }
