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]

In this regard, it unusually tolerates sulfur compounds, which poison noble metal catalysts.

[1] Rhenium(VII) sulfide decomposes when heated.
