|Section2= |Section3= |Section4= }} Tellurium tetrafluoride, TeF4, is a stable, white, hygroscopic crystalline solid and is one of two fluorides of tellurium. The other binary fluoride is tellurium hexafluoride.〔''Inorganic Chemistry'',Egon Wiberg, Arnold Frederick Holleman Elsevier 2001 ISBN 0-12-352651-5〕 The widely reported Te2F10 has been shown to be F5TeOTeF5 〔 There are other tellurium compounds that contain fluorine, but only the two mentioned contain solely tellurium and fluorine. Tellurium difluoride, TeF2, and ditellurium fluoride, Te2F are not known.〔 ==Preparation== Tellurium tetrafluoride can be prepared by the following reaction: :TeO2 + 2SF4 → TeF4 + 2SOF2 It is also prepared by reacting nitryl fluoride with tellurium or from the elements at 0 °C or by reacting selenium tetrafluoride with tellurium dioxide at 80 °C. Fluorine in nitrogen can react with TeCl2 or TeBr2 to form TeF4. PbF2 will also fluorinate tellurium to TeF4. 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「Tellurium tetrafluoride」の詳細全文を読む スポンサード リンク
