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:

$\mathrm {2Re+7S\ {\xrightarrow {\Delta }}\ Re_{2}S_{7}}$

• Treating rhenium(VII) oxide with hydrogen sulfide:

$\mathrm {Re_{2}O_{7}+7H_{2}S\ {\xrightarrow {\Delta }}\ Re_{2}S_{7}+7H_{2}O}$

Reactions

Rhenium(VII) sulfide decomposes when heated in vacuum:

$\mathrm {Re_{2}S_{7}\ {\xrightarrow {600^{o}C}}\ 2ReS_{2}+3S}$

It is converted to oxide when heated in air:

$\mathrm {2Re_{2}S_{7}+21O_{2}\ {\xrightarrow {\Delta }}\ 2Re_{2}O_{7}+14SO_{2}}$
