Reaction of WF6 with AsR3 (R = Me or Et) in anhydrous CH2Cl2 at low temperature forms the neutral seven-coordinate, [WF6(AsR3)] (R = Me, Et), the first arsine complexes of WF6, whilst o-C6H4(EMe2)2 (E = P, As) produces [WF4{o-C6H4(EMe2)2}2][WF7]2. Crystal structures show the latter contain dodecahedral cations, and present the highest oxidation state metal fluoride complexes known (and the highest possible for tungsten) with soft neutral phosphine and arsine coordination.
六氟化钨与 AsR3（R = Me 或 Et）在无水 CH2Cl2 中于低温下反应，形成中性的七配位化合物 [WF6(AsR3)]（R = Me，Et），这是六氟化钨的第一个胂配合物，而邻苯二甲酸二甲酯（EMe2）2（E = P，As）则生成 [WF4{o-C6H4(EMe2)2}2][WF7]2。晶体结构表明后者含有十二面体阳离子，并呈现出已知的最高氧化态金属氟化物配合物（对于钨来说也是可能的最高氧化态），具有软的中性膦和胂配位。
