Abstract

Redox reactions of [M(eta(6)-1,3,5-Me(3)C(6)H(3))(2)], [Mmes(2)], (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)(2)Nb(mu-I)(2)Re(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 d(7) and d(3) configurations, respectively, with a Nb-Re distance (average) of 2.921(4) Angstrom.
