C-H center dot center dot center dot pi interactions in the metal-porphyrin complexes with chelate ring as the H acceptor
Апстракт
Specific C-H(...)pi interactions with the pi-system of porphyrinato chelate ring were found in crystal structures of transition metal complexes from the Cambridge Structural Database and statistical analysis of geometrical parameters for intramolecular and intermolecular interactions was done. By density functional theory calculations on a model system it was evaluated that an interaction energy is above 1.5 kcal/mol and that the strongest interaction occurs when the distance between hydrogen atom and the center of the chelate ring is 2.6 Angstrom. This prediction is in good agreement with the distances for intermolecular interactions found in the crystal structures. In many cases the intramolecular interaction distances are much shorter than 2.6 Angstrom, and these short distances are caused by geometrical constrains. The C-H(...)pi interactions with chelate ring of porphyrinato ligand can influence the structure, contribute to its stability, and play some role in the function of biom...olecules with metalo porphyrins.
