Rhenium(VII) sulfide is a chemical compound with the formula Re2S7. It has a complex structure, but can be synthesized from direct combination of the elements:[1] [math]\ce{ 2Re{} + 7S ->[{}\atop\Delta] Re2S7 }[/math]Alternatively, rhenium(VII) oxide reacts with hydrogen sulfide in 4N HCl to the same end:[2] [math]\ce{ Re2O7{} + 7H2S ->[{}\atop\Delta] Re2S7{} + 7H2O }[/math]

The compound catalyses the reduction of nitric oxide to nitrous oxide and hydrogenation of double bonds. In this regard, it unusually tolerates sulfur compounds, which poison noble metal catalysts.[1]

Rhenium(VII) sulfide decomposes when heated. In vacuum, it generates rhenium(IV) sulfide:

[math]\displaystyle{ \mathrm{Re_2S_7 \ \xrightarrow{600^oC}\ 2ReS_2 + 3S } }[/math]

In air, the sulfur oxidizes to sulfur dioxide:

[math]\displaystyle{ \mathrm{2Re_2S_7 + 21O_2 \ \xrightarrow{\Delta}\ 2Re_2O_7 + 14SO_2 } }[/math]
