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] Alternatively, rhenium(VII) oxide reacts with hydrogen sulfide in 4N HCl to the same end:[2]

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:

In air, the sulfide oxidizes to sulfur dioxide:
