Weak Intermolecular Interactions

Utilizing dispersion-corrected density functional theory (DFT) calculations, we demonstrate the weak intermolecular interactions of phenylenediamine dimer (pdd) clusters, emphasizing the local lowest energy structures and decomposition of interaction energies by natural bond orbital (NBO) and atoms in molecule (AIM) analyses.

A theoretical study to elucidate the mechanistic aspects involved in the tosylation-cyclization reaction of diastereomeric phytosphingosines 1a-1d to jaspines 4a-4d is presented. The stereochemistry of the starting stereoisomers is crucial for the development of weak interactions, both in the reactants and in the transition states. The analysis of the energy barriers of each elementary reaction is consistent with the observed reluctance of tosylate 2d to undergo cyclization. In addition, the initial tosylation can be identified as the limiting step in cyclizations from 1a and 1b.

The factors that affect the structures and stability of the adducts of cisamminedichloro(2-methylpyridine)platinum(II) with a duplex DNA were probed into by the mixed quantum chemistry and molecular mechanics (QM/MM), molecular dynamics (MD) and molecular mechanics (MM) methods. It shows that the coordinate bonds between Pt and N7G, the hydrogen bond between the amine and O6G, the weak interactions between drug molecule and DNA and the positive electron charge center position of the drug molecule in the adduct affect the stability and the steric selection of the adduct greatly. And in return the structure of the adduct determine the comparatively strengths of the coordinate bonds in the adduct.

A new highly photo-switchable ligand furnishes supramolecular tetrahedral nanomagnets with Ln(iii) ions (Ln = Dy, Tb). Intramolecular weak interactions define the conformation of the ligand, quenching the photochromic activity.
