Nature of anion-templated π+–π+ interactions

Author affiliations


Interaction between positively charged aromatic groups (π+–π+) is characterized by anti-parallel, displaced-stacked structures in the presence of counteranions. Binding energies of pyridinium, N-methylpyridinium and N-methylimidazolium dimers are much larger than that of benzenepyridine (π–π) and pyridinium–benzene+–π). Stabilization is attributed to attractive electrostatic interaction with significant dispersion contribution.
