Abstract:
Supramolecular chemistry is mainly concerned with non-covalent interactions, also termed as supramolecular interactions.1 It encompasses both attractive and repulsive effects within molecules. Interestingly, an entire supramolecular system is held together by interplay of all possible supramolecular interactions present in the system. The interactions can be classified into (a) ion-ion, (b) ion-dipole, (c) dipole-dipole, (d) hydrogen bonding, (e) cation-?, (f) anion-?, (g) ?-?, (h) van der Waals and (i) closed-shell interactions. These can arise due to both, host and guest as well as the surroundings such as crystal lattice arrangement, ion-pairing, solvation etc.
