Abstract
Redox reactions of [M(η6-1,3,5-Me3C6H3)2], [Mmes2], (M 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 a Nb-Re distance (average) of 2.921(4) Å. © 1993.File in questo prodotto:
