dc.description.abstract | We compare aromatic pi interactions with aliphatic pi interactions of double- and triple-bonded pi systems and non-pi stacking interactions of single-bonded sigma systems. The model dimer systems of acetylene (C2H2)(2), ethylene (C2H4)(2), ethane (C2H6)(2), benzene (C6H6)(2), and cyclohexane (C6H12)(2) are investigated. The ethylene dimer has large dispersion energy, while the acetylene dimer has strong electrostatic energy. The aromatic pi interactions are strong with particularly large dispersion and electrostatic energies, which would explain why aromatic compounds are frequently found in crystal packing and molecular self-engineering. It should be noted that the difference in binding energy between the benzene dimer (aromatic-aromatic interactions) and the cyclohexane dimer (aliphatic-aliphatic interactions) is not properly described in most density functionals. | - |
