It is a yellow low melting solid, and is the only thermally stable metal heptafluoride. It has a distorted pentagonal bipyramidal structure similar to IF7, which was confirmed by neutron diffraction at 1.5K. The structure is non-rigid as evidenced by electron diffraction studies. It can be prepared from the elements at 400 °C: :2Re + 7 F2 → 2 ReF7 With fluoride donors such as CsF, the ReF8− anion is formed, which has a square antiprismatic structure. With antimony pentafluoride, SbF5, a fluoride acceptor, the ReF6+ cation is formed.〔 ==References== 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 heptafluoride」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
