Redox reactions of 6-1,3,5-Me3C6H3)2>, , (M=V or Nb) with (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 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) Angstroem.
