Nitrogen family physical behavior

The physical basis for this supramolecular motif can be ascribed to a desire of the system to maximize electrostatic interactions. The pyridyl nitrogen atom and the -OH moiety constitute the best hydrogen-bond acceptor and donor,respectively, and these moieties display a strong preference for each other. The key to understanding and predicting the supramolecular behavior of a family of (N-heterocycle/amide) SRs is the relative hydrogen-bonding (HB) ability" (based on basicity and molecular electrostatic surface potential) of the N-heterocycle (Scheme 4).
