1H NMR spectra (500 MHz/CD3CN) of a) A′o; b) Pi; c) [Pd2 A′o 2 Pi 2]4+ obtained by heating a 1:1:1 mixture of A′o, Pi and PdII to 70 °C; d) ESI‐MS spectrum of [Pd2 A′o 2 Pi 2+n BF4](4‐n)+ with n=0, 1 (*=[Pd2 A′o 3 Pi 2]4+). X‐ray structure of [(BF4)2.4Cl0.6@Pd4 Po 8]5+ with both found anions shown superimposed in the central cavity. Hydrogen atoms and unbound counter‐ions were removed for clarity; e) side view, showing the Pd⋅⋅⋅Pd distances, f) top view; g) a close‐up view of the outer picoline4‐Pd fragment of the structure.
