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

  • Direct combination of rhenium and sulfur:
{\mathrm  {2Re+7S\ {\xrightarrow  {\Delta }}\ Re_{2}S_{7}}}
{\mathrm  {Re_{2}O_{7}+7H_{2}S\ {\xrightarrow  {\Delta }}\ Re_{2}S_{7}+7H_{2}O}}

Reactions

Rhenium(VII) sulfide decomposes when heated in vacuum:

{\mathrm  {Re_{2}S_{7}\ {\xrightarrow  {600^{o}C}}\ 2ReS_{2}+3S}}

It is converted to oxide when heated in air:

{\mathrm  {2Re_{2}S_{7}+21O_{2}\ {\xrightarrow  {\Delta }}\ 2Re_{2}O_{7}+14SO_{2}}}
