AI Article Synopsis

  • The study examined CH/pi interactions between acetylacetonato ligands and phenyl rings, using data from the Cambridge Structural Database as well as quantum chemical calculations.
  • The acetylacetonato ligand can function as a hydrogen atom donor or acceptor, influencing its interactions with metal in chelate rings.
  • Stronger interactions were found when the acetylacetonato acted as a donor with soft metals, while this trend did not hold for acceptor interactions.

Article Abstract

CH/pi interactions between the coordinated acetylacetonato ligand and phenyl rings were analyzed in the crystal structures from the Cambridge Structural Database and by quantum chemical calculations. The acetylacetonato ligand may engage in two types of interactions: it can be hydrogen atom donor or acceptor. The analysis of crystal structures and calculations show that interactions with the acetylacetonato ligand acting as hydrogen atom donor depend on the metal in an acetylacetonato chelate ring; the chelate rings with soft metals make stronger interactions. The same trend was not observed in the interactions where the acetylacetonato chelate ring acts as the hydrogen atom acceptor.

High-resolution crystal structures of lysozyme in the presence of the potential drug V O(acetylacetonato) under two different experimental conditions have been solved. The crystallographic study reveals the loss of the ligands, the oxidation of V to V and the subsequent formation of adducts of the protein with two different polyoxidovanadates: [V O ] , which interacts with lysozyme non-covalently, and the unprecedented [V O (NO )] , which is covalenty bound to the side chain of an aspartate residue of symmetry related molecules.

π-π Interactions are established as a powerful supramolecular tool, whereas the usability of CH-π interactions has been rather limited so far. Here we present (i) selective binding of planar polyaromatics and (ii) effective isolation of planar metal complexes by a polyaromatic capsule, utilizing multiple CH-π interactions. In the spheroidal cavity, one molecule of large and medium-sized polyaromatic molecules (i.
