L'òxid de reni(VII) es produeix quan el reni metàl·lic o els seus òxids o sulfurs s'oxiden a 500 °C-700 °C a l'aire. És molt reactiu amb l'aigua i es dissol en aigua per formar àcid perrènic. És un precursor del triòxid de metilreni (MTO), un catalitzador de reaccions d'oxidació. També es fa servir en síntesi orgànica com a catalitzador per a l'etenòlisi, la reducció de carbonil i la reducció d'<a href="/wiki/Amida_(compost_qu%C3%ADmic)" title="Amida (compost químic)">amides</a>.<sup id="cite_ref-:6_16-0" class="reference"><a href="#cite_note-:6-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup> </p><p>L'<a href="/w/index.php?title=%C3%92xid_de_reni(VI)&action=edit&redlink=1" class="new" title="Òxid de reni(VI) (encara no existeix)">òxid de reni(VI)</a> <span class="mwe-math-element"><span class="mwe-math-mathml-inline mwe-math-mathml-a11y" style="display: none;"><math xmlns="http://www.w3.org/1998/Math/MathML" alttext="{\displaystyle {\ce {ReO3}}}"> <semantics> <mrow class="MJX-TeXAtom-ORD"> <mstyle displaystyle="true" scriptlevel="0"> <mrow class="MJX-TeXAtom-ORD"> <msubsup> <mtext>ReO</mtext> <mrow class="MJX-TeXAtom-ORD"> <mn>3</mn> </mrow> <mrow class="MJX-TeXAtom-ORD"> <mspace width="0pt" height="0pt" depth=".2em"></mspace> </mrow> </msubsup> </mrow> </mstyle> </mrow> <annotation encoding="application/x-tex">{\displaystyle {\ce {ReO3}}}</annotation> </semantics> </math></span><img src="https://wikimedia.org/api/rest_v1/media/math/render/svg/c419dbd9a8981031cbb869a249a1c56ad86ac13b" class="mwe-math-fallback-image-inline mw-invert skin-invert" aria-hidden="true" style="vertical-align: -1.005ex; width:5.605ex; height:2.843ex;" alt="{\displaystyle {\ce {ReO3}}}" /></span> és un sòlid vermellós amb una brillantor metàl·lica, que s'assembla al coure i que presenta una estructura semblant a la <a href="/wiki/Perovskita" title="Perovskita">perovskita</a> (ABO₃).
