    • Although a sound structural assignment of the minor species present in solution at low temperature is difficult, it is conceivable that these resonances are due to oligomeric palladium complexes traversing the formation of the tetramer 2.

    • Prolonged drying of compound 5 should be avoided in order to prevent dehydroalogenation in the solid state.

    • The peaks observed in addition to those accounted for in the simulated spectrum may be attributed to the 10.4% and 1.4% of molecules containing three and four magnetically active platinums, respectively.

    • 1H} NMR NOESY-EXSY experiments carried out at 180 K were not decisive in confirming the existence of the conformational equilibrium since no clear exchange cross-peaks could be assigned. The major problem of these experiments was the shortness of the FID (ca. 30 ms) that forced us to use mixing times shorter than 20 ms, a time possibly insufficient to warrant the envisaged exchange to occur.
