Abstract
First insights into the coordinative behavior of a calix[6]tren ligand are presented. Reaction with zinc perchlorate led to a dicationic complex with the metal ion strongly bound to the tren cap. It presents a unique coordination site accessible for a small coordinating molecule that is controlled by the calixarene cavity. Hence, X‐ray analysis and solution 1H NMR studies evidenced a five‐coordinate complex thanks to the coordination of a guest ligand, MeCN, included deep inside the calixarene cavity. Interestingly, the metal ion is bound in an asymmetrical environment in both the solid state and in solution. It is also particularly reluctant, and resistant, to anion binding.
