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.^[1]

Synthesis

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

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

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}}
