Reaction of [Cp'2NbTe2H] (1) (Cp' = eta (5)-tBUC(5)H(4)) with [W(CO)(6)] in decane at 140 degreesC gives red [((Cpl(2)Nb)(2)WTe4)W(CO)(4)] (2), whereas in the reaction of 1 with [Cr(CO)(6)] green-black [Cp'4Nb2Te2] (3) is formed. The crystal structures of 2 and 3 have been determined. The structure of 2 contains a slightly distorted WTe4 tetrahedron to which two niobocene fragments and one W(CO)(4) group are coordinated. The crystal structure determination of 3 reveals the presence of two Cp'Nb-2 units bridged by two Te atoms. Complex 2 represents the first example of an organometallic derivative of the unknown WTe42- anion.
