A novel C-symmetric propeller-shaped vanadium(IV/V) oxide cluster complex, [VO(4,4'- Bubpy)] (V'), has been synthesized from the reaction of the windmill-shaped vanadium(V) oxide cluster complex [VO(4,4'- Bubpy)] (V) with PPh under N, whereas refluxing V in methanol or ethanol under N provides tetranuclear oxido(alkoxido)vanadium(IV/V) complexes [VO(OR)(4,4'- Bubpy)] [R = Me (V'-Me) and Et (V'-Et)]. The mixed-valent vanadium(IV/V) clusters V' and V' are converted back to V under O. Interconversions of V' and the oxido(alkoxido)vanadium(V) complexes [VO(OMe)(4,4'- Bubpy)] (V) and [VO(OEt)(4,4'- Bubpy)] (V-Et) are also presented.
一种新型的 C 对称螺旋桨状钒(IV/V)氧化物簇合物[VO(4,4'-Bubpy)](V'),是通过风车状的钒(V)氧化物簇合物[VO(4,4'-Bubpy)](V)与 PPh 在 N 下反应合成的,而在 N 下回流 V 于甲醇或乙醇中则提供四核氧代(烷氧基)钒(IV/V)配合物[VO(OR)(4,4'-Bubpy)] [R = Me(V'-Me)和 Et(V'-Et)]。混合价态的钒(IV/V)簇合物 V'和 V'在 O 下被转化回 V。V'和氧代(烷氧基)钒(V)配合物[VO(OMe)(4,4'-Bubpy)](V)和[VO(OEt)(4,4'-Bubpy)](V-Et)之间也存在相互转化。
