AB  - Analysis of crystal structure data deposited in the Cambridge Structural Database (CSD) has shown that aromatic rings tend to stack with square planar transition metal complexes when they contain chelate rings. In these interactions, the orientation between chelate and aryl ring is a parallel-displaced orientation, like stacking interactions between aromatic molecules. In fused systems containing chelate and aryl rings, the aryl rings prefer to stack with the chelate rather than with other aryl rings. Quantum chemical calculations show that chelate-aryl stacking is stronger than aryl-aryl stacking. Interaction energies of six-membered chelates of the acetylacetonato type with benzene exceed -6 kcal/mol (CCSD(T)/CBS), more that twice as strong as that for two benzene molecules. Further analysis of the CSD has shown that chelate rings, both isolated and fused stack with other chelate rings. These chelate-chelate stacking interactions can have both face-to-face and parallel-displaced geometries, unlike the stacking interactions between aromatic molecules, for which face-to-face geometry is not typical. Chelate-chelate stacking is stronger than aryl-aryl stacking and stronger even than chelate-aryl stacking. Stacking energies between six-membered chelates of acetylacetonato type exceed -9 kcal/mol, while those between five-membered dithiolene chelates are even stronger. Calculated interaction energies and analysis of supramolecular structures have shown that chelate-chelate and chelate-aryl stacking must be considered in understanding the packing and organization of supramolecular systems and crystal engineering.

AB  - The role of aromatic and nonaromatic amino acids in amyloid formation has been elucidated by calculating interaction energies between -sheets in amyloid model systems using density functional theory (B3LYP-D3/6-31G*). The model systems were based on experimental crystal structures of two types of amyloids: (1)with aromatic amino acids, and (2)without aromatic amino acids. Data show that these two types of amyloids have similar interaction energies, supporting experimental findings that aromatic amino acids are not essential for amyloid formation. However, different factors contribute to the stability of these two types of amyloids. In the former, the presence of aromatic amino acids significantly contributes to the strength of interactions between side chains; interactions between aromatic and aliphatic side chains are the strongest, followed by aromatic-aromatic interactions, while aliphatic-aliphatic interactions are the weakest. In the latter, that is, the amyloids without aromatic residues, stability is provided by interactions of aliphatic side chains with the backbone and, in some cases, by hydrogen bonds.
