'''酸化レニウム(IV)'''(Rhenium(IV) oxide)は、化学式ReO<sub>2</sub>の[[無機化合物]]である。'''二酸化レニウム'''とも呼ばれる。灰色から黒色の結晶性固体で、[[触媒]]等として用いられる。[[金紅石]]型の構造を取る。

==合成と反応==
酸化レニウム(IV)は、[[均等化]]によって生じる<ref>G. Glemser "Rhenium (IV) Oxide" Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G. Brauer, Academic Press, 1963, NY. Vol. 1. p. 1480.</ref>。
: <chem>2 Re2O7\ + 3 Re -> 7 ReO2</chem>

高温では、逆に[[不均化]]が起こる。
: <chem>7 ReO2 -> 2 Re2O7\ + 3 Re</chem>

アルカリ性の[[過酸化水素]]及び[[酸化性酸]]との反応で、[[過レニウム酸]]が生じる<ref>{{cite web|url=http://www.aaamolybdenum.com/RheniumDioxide.html |title=RHENIUM DIOXIDE - Manufacturer |publisher=Aaamolybdenum.com |date= |accessdate=2012-08-06}}</ref>。融解[[水酸化ナトリウム]]中で[[レニウム酸ナトリウム]]を形成する<ref>G.
