Molecular balances based on the dibenzobicyclo[3.2.2]nonane template enable probing of the competition between halogen-π and CH-π interactions. Structural, NMR spectroscopic, and computational analyses revealed that the π system can favorably interact both with C-X or C-H functionalities, depending on the size of the functional group.
