WF6 与 AsR3 (R = Me 或 Et) 在无水 CH2Cl2 中低温反应形成中性七配位 [WF6(AsR3)] (R = Me, Et),即 WF6 的第一个砷化氢配合物,而 o-C6H4(EMe2)2 (E = P, As) 生成 [WF4{o-C6H4(EMe2)2}2][WF7]2。晶体结构显示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络合物(对于钨来说是最高氧化态),具有软中性膦和胂配位。
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.
