Chemical compound

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] Failed to parse (syntax error): {\displaystyle \ce{2Re{} + 7S ->[{}\atop\Delta] Re2S7}} Alternatively, rhenium(VII) oxide reacts with hydrogen sulfide in 4N HCl to the same end:[2] Failed to parse (syntax error): {\displaystyle \ce{Re2O7{} + 7H2S ->[{}\atop\Delta] Re2S7{} + 7H2O}}

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:

R e 2 S 7 -> 600 o C 2 R e S 2 + 3 S {\displaystyle \mathrm {Re_{2}S_{7}\ {\xrightarrow {600^{o}C}}\ 2ReS_{2}+3S} }

In air, the sulfide oxidizes to sulfur dioxide:

2 R e 2 S 7 + 21 O 2 -> Δ 2 R e 2 O 7 + 14 S O 2 {\displaystyle \mathrm {2Re_{2}S_{7}+21O_{2}\ {\xrightarrow {\Delta }}\ 2Re_{2}O_{7}+14SO_{2}} }
