Reaction of [(Cp2Nb)-Nb-#(Te2H)] (1(#)) (Cp-# =Cp* (C5Me5) or Cp-x (C5Me4Et)) with [Fe-2(CO)(9)] in boiling toluene gives [Fe-3(mu(2)-H)(mu(3)-Te)(Co)(9)][Cp-2(#) Nb(Co)(2)] (2) (Cp-# =Cp*) and (3) (Cp-# =Cp-x) in 33 and 39% yield, respectively. The crystal structure of 3 contains the already known [Fe3HTe(CO)(9)](-) anion and a [(Cp2Nb)-Nb-x(CO)(2)](+) cation in a 1:1 ratio. The latter belongs to the class of bent metallocenes in which the Nb(CO), plain bisects the cation. For the first time, localization of the hydrogen in the solid state as a mu(2)-bridge in the cluster anion has been established. (C) 2000 Elsevier Science S.A. All rights reserved.
