四氟氧化钨是一种无机化合物，化学式为WOF₄，易水解。其反应活性类似于六氟化钨。^[4]

制备

WOF₄可由氟气于230~400℃和三氧化钨反应得到：^[4]

WO₃ + 2 F₂ → WOF₄ + 2 O₂

它也可以由钨和氧气和氟气的混合物在高温下反应而成，^[1]六氟化钨的部分水解也能产生WOF₄：^[5]

{\ce {WF6 + H2O -> WOF4 + 2 HF}}

四氯氧化钨和氟化氢的反应也会产生WOF₄：^[3]

{\ce {WOCl4 + 4HF -> WOF4 + 4HCl}}

WOF₄还可以由氟化铅和三氧化钨在700 °C下反应而成：^[3]

{\ce {2PbF2 + WO3 -> WOF4 + 2PbO}}

性质

四氟氧化钨是无色固体，会水解成钨酸：^[1]^[5]

{\ce {WOF4 + 2 H2O -> WO3 + 4 HF}}

固态的WOF₄之前假定为四聚体结构，^[6]后来受到光谱学研究的质疑。在气态下，该分子具有单体结构。^[7]四氟氧化钨可以和乙腈等配体形成配合物。^[8]^[9]
