V or Nb) with [MX(CO)5] (M Mn, X Cl, Br, or I; M Re, X Br or I) leading to oxidation of the organometallic of Group 5 have been investigated. The crystal structure of [mes(CO)2Nb(μ-I)2Re(CO)3] 1b, has been solved by X-ray diffraction methods; the organometallic derivative can best be described as containing rhenium(0) and niobium(II) centres of d7 and d3 configurations, respectively, with
的氧化还原反应[M(η 6 -1,3,5--ME 3 Ç 6 ħ 3)2 ],[促膝2 ],(MV或Nb)的用[MX(CO)5 ](M的Mn,已经研究了X 5 Cl,Br或I; M 3 Re,X 18 Br或I)导致第5族有机金属氧化的情况。[mes(CO)2 Nb(μ-I)2 Re(CO)3 ] 1b的晶体结构已通过X射线衍射法解析;最好将有机金属衍生物描述为包含d 7和d 3构型的rh(0)和铌(II)中心,Nb-Re距离(平均)为2.921(4)。
