Competition of intermolecular interactions in the self-assembly of co-crystals of trifluoro-meta-arylenediamines (benzene, nitrobenzene, pyridine) with 12-, 15-, 18-membered crown ethers

Arylenediamine acceptor properties and crown ether size affect the stoichiometry and supramolecular structure of co-crystals by means of restructuring of guest–host and guest–guest contacts, changing packing enthalpies and bonding energies.
