Cover Story: A mono-nuclear “two wall” aryl-extended caxli[4]pyrrole receptor decorated with an acetylide–gold(I)–PTA complex at its upper rim is synthesized. The binding properties of the unprecedented receptor and their synthetic precursors (R= I and ethynyl) towards chloride are studied in dichloromethane and acetone. The calculated ESP values at the centers of the aromatic ring and at the para‐substituent (R) of the differently substituted aromatic walls were not enough to explain the dissimilar free energies of binding of the 1:1 chloride complexes exclusively in terms of repulsive anion–π interactions. The calix[4]pyrrole acetylide gold(I) receptor binds chloride exclusively in the cone conformation, and the presence of free chloride in solution induces the formation of a gold(I)–anionic calix[4]pyrrole dimer.
