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.

Synthesis

Direct combination of rhenium and sulfur:

2 R e + 7 S → Δ R e 2 S 7

Treating rhenium(VII) oxide with hydrogen sulfide:

R e 2 O 7 + 7 H 2 S → Δ R e 2 S 7 + 7 H 2 O

Rhenium(VII) sulfide decomposes when heated in vacuum:

R e 2 S 7 → 600 o C 2 R e S 2 + 3 S

It is converted to oxide when heated in air:

2 R e 2 S 7 + 21 O 2 → Δ 2 R e 2 O 7 + 14 S O 2
