Electron localization in a mixed-valence diniobium benzene complex.

ABSTRACT: Reaction of the neutral diniobium benzene complex {[Nb(BDI)N ^t Bu]₂(μ-C₆H₆)} (BDI = N,N'-diisopropylbenzene-β-diketiminate) with Ag[B(C₆F₅)₄] results in a single electron oxidation to produce a cationic diniobium arene complex, {[Nb(BDI)N ^t Bu]₂(μ-C₆H₆)}{B(C₆F₅)₄}. Investigation of the solid state and solution phase structure using single-crystal X-ray diffraction, cyclic voltammetry, magnetic susceptibility, and multinuclear NMR spectroscopy indicates that the oxidation results in an asymmetric molecule with two chemically inequivalent Nb atoms. Further characterization using density functional theory (DFT) ca
