Tetra‐armed cyclen ( 1 ) bearing two 4‐(4′‐pyridyl)benzyl and two 3,5‐difluorobenzyl groups and its Ag + complexes were prepared and structurally characterized. The complexes formed between 1 and Ag + undergoes a reversible structural transformation between a 2:2 dimeric complex and a 3:5 pentacyclic trefoil complex with changes in the Ag + / 1 molar ratio. It was also revealed that the 3:5 trefoil complex could encapsulate benzene and [D 6 ]benzene selectively in solid‐state. The benzene‐included structures are stabilized by C−H⋅⋅⋅F−C interactions between the benzene molecule and the ligand molecule.
