This gray to black crystalline solid is a laboratory reagent that can be used as a catalyst. It adopts the rutile structure. ==Synthesis and reactions== It forms via comproportionation:〔G. Glemser "Rhenium (IV) Oxide" Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G. Brauer, Academic Press, 1963, NY. Vol. 1. p. 1480.〕 :2 Re2O7 + 3 Re → 7 ReO2 At high temperatures it undergoes disproportionation: : 7 ReO2 → 2 Re2O7 + 3 Re It forms perrhenates with alkaline hydrogen peroxide and oxidizing acids. In molten sodium hydroxide it forms sodium rhenate:〔G. Glemser "Sodium Rhenate (IV)" Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G. Brauer, Academic Press, 1963, NY.
