Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

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:
