It is the only stable trioxide of the Group 7 elements (Mn, Tc, Re). ==Preparation, structure== Rhenium trioxide can be formed by reducing rhenium(VII) oxide with carbon monoxide. 〔H. Nechamkin, C. F. Hiskey, "Rhenium(VI): Oxide (Rhenium Trioxide)" Inorganic Syntheses, 1950 Volume 3, pp. 186-188. 〕 :Re2O7 + CO → 2 ReO3 + CO2 Re2O7 can also be reduced with dioxane.〔 Rhenium oxide crystallizes with a primitive cubic unit cell, with a lattice parameter of 3.742 Å (374.2 pm). The structure of ReO3 is similar to that of perovskite (ABO3), without the large A cation at the centre of the unit cell. Each rhenium center is surrounded by an octahedron defined by six oxygen centers. These octahedra share corners to form the 3-dimensional structure. The coordination number of O is 2 because each oxygen atom has 2 neighbouring Re atoms.〔, p. 1047.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「rhenium trioxide」の詳細全文を読む スポンサード リンク
