    • Whenever a two-electron process appears as a single voltammetric peak, the position (voltage) of the peak is governed by the transfer of the first electron. This fact has been derived explicitly for the irreversible case; see R. G. Compton, C. E. Banks, Understanding Voltammetry, 2 nd ed., Imperial College Press, London, 2011, pp. 142-147. For the purpose of our study, it is not necessary that the product of the first electron transfer be a stable or long-lived species.

    • There are numerous reasons why voltammetric processes appear to be irreversible. It may simply be an issue of the slow rate of heterogeneous electron transfer; however, if this irreversibility is caused by a follow-on chemical step, such as a re-arrangement or even catastrophic decomposition, it is well-known that the observed peak voltages can be affected, depending on the rate of the chemical step. See:, A. J. Bard, L. R. Faulkner, Electrochemical Methods, 2 nd ed., Wiley, New York, 2001, pp. 496-510. In the absence of detailed knowledge of what these follow-on reactions are, obtaining a good correlation with the computed values gives us confidence that, if such reactions affect the data, they will at least affect the studied series of homologous molecules to a similar extent.

    • . and the energy differences between the different isomers are very small. Thus, for the calculation of ionization energies, it seems reasonable to assume that the calculation of possible further isomers for the halogenated 1-carba-closo-dodecaborates would not change these general results.

    • SWV, specifically the technique that is popularly known as Osteryoung square-wave voltammetry, is an extremely useful technique that minimizes electrode fouling and provides information that corresponds to cyclic voltammetry at a significantly different scan rate. For a fully irreversible process, the position of the SW peak maximum in the difference trace (Figure 4) is expected to be effectively the same as that of the maximum in the forward trace. On this point, see Figure 2.6 on page 18 of, V. Mirčeski, Š. Komorsky-Lovric̈, M. Lovric̈, Square-Wave Voltammetry, Springer, Berlin, 2007. The generally good agreement between the CV and SWV data for most of the analytes is an indication that the reported peak potentials are probably not greatly affected by kinetic differences in any operative follow-on chemical reactions.

    • - showed different behavior compared to the other anions. This difference might be a result of the weak B-I bond, as well as their different electronic structures. The different behavior of the periodinated anion needs further investigation and, therefore, all of the values regarding this anion should be treated tentatively.

    • - displayed complex behavior in their cathodic scans at more-negative potentials. We attribute this complex behavior to follow-on reactions that are likely induced by halide elimination from the dianions. The nature of these follow-on reactions was not investigated further. For details, see the Supporting Information, Section S1.2.2.
