摘要：

The TCNX ligands TCNE and TCNQ reacted in toluene with Cp2V in the presence of B(C6F5)(3) to yield, depending on the stoichiometry, the divanadium(III) complexes [(Cp2V)(2){(C6F5)3B center dot(mu(4)-TCNX)center dot B(C6F5)(3)}] (X = Q (3), E (4)) or the Vanadium(IV) dimers [Cp2V{(C6F5)(3)B center dot(mu 4-TCNX)center dot B(C6F5)(3)}](2) (X = E (5), Q (6)), all containing [TCNX](2-) ligands sigma-bonded to Vanadium through a nitrile nitrogen, as revealed by crystallographic (for 3-5) and magnetic studies (for 3-6).
