Synthesis, characterization, and electrochemistry of tertiary phosphine complexes of niobium and tantalum halide clusters

Monodentate tertiary phosphines react with the hydrated niobium and tantalum chloride clusters M6Cl14·8H2O and M6Cl15·7H2O to produce the complexes of stoichiometry (M6Cl12)Cl2(PR3)4. Electrochemical measurements, using cyclic voltammetry and coulometry techniques, reveal the presence of three couples, two one-electron oxidations and a single reduction. The monoanions [(M6Cl12)Cl2(PR3)4] - are formally derivatives of the previously unknown (M6Cl12)+ core. The chemical oxidation of (Nb6Cl12)Cl2(P-n-Pr3)4 to [(Nb6Cl12)Cl2(P-n-Pr3) 4]PF6 occurs when NOPF6 is used as the oxidant. The oxidations of (Ta6Cl12)Cl2(P-n-Pr3)4 to [(Ta6Cl12)Cl2(P-n-Pr3) 4]PF6 and [(Ta6Cl12)Cl2(P-n-Pr3) 4](PF6)2 have also been accomplished. When appropriate, the spectral properties (infrared, electronic absorption, X-ray photoelectron, and ESR) of these new complexes have been investigated.
