|Section2= |Section3= |Section4= |Section7= }} Vanadium(IV) fluoride (VF4) is an inorganic compound of vanadium and fluorine. It is paramagnetic yellow-brown solid that is very hygroscopic.〔 Unlike the corresponding vanadium tetrachloride, the tetrafluoride is not volatile because it adopts a polymeric structure. It decomposes before melting. ==Preparation and reactions== VF4 can be prepared by treating VCl4 with HF: :VCl4 + 4 HF → VF4 + 4 HCl It was first prepared in this way.〔Otto Ruff, Herbert Lickfett "Vanadinfluoride" Chemische Berichte 1911, vol. 44, pages 2539–2549. 〕 It decomposes at 325 °C, undergoing disproportionation to the tri- and pentafluorides:〔 :2 VF4 → VF3 + VF5 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「vanadium tetrafluoride」の詳細全文を読む スポンサード リンク
