“…[21] A comparison of the skeleton (Table 3) indicates a fairly robust core in which the nature of the halide does not perturb the bond distances within the experimental uncertainties. In all cases, the Pd-X distances indicate strong ionic interactions and vary as expected (Cl Ͻ Br Ͻ I).…”

“…Its RDE voltammogram is depicted in Figure 1 (trace a) and exhibits two closely spaced waves for oxidation and reduction labelled AЈ 1 + can be seen (δ = -6.4 ppm). [20][21][22] 31 P NMR spectroscopic data (δ = -6.14 ppm in [D 6 ]acetone) as well as the formation of Bz 2 (44 % based upon GCMS data) and PhMe. [23] During the course of this investigation, crystals of Pd 3 (Br) + suitable for X-ray analysis were obtained and investigated (see below).…”

“…The set of two signals at 4.8 and 4.9 ppm is the characteristic pattern observed for the CH 2 P 2 protons when both sides of the Pd 3 plane are inequivalent. [29] However, the septet expected for the hydride (coupling with six equivalent 31 P nuclei) is yet to be found. It is anticipated that this weak signal (intensity of one H distributed between the seven peaks) is hidden under the stronger resonances of the Bu 3 NH + co-product, which virtually screens the spectral window between 1 and 4 ppm.…”

“…[11] Of particular interest in our current work is the binding of halide ions onto this [Pd 3 ] 2 + species leading to very stable architectures. [12] Related to this high affinity for halides, the cluster is also reactive towards the carbon-halogen bond, which led to important new catalytic processes in organic electrosynthesis.
