Аннотация

Topological analyses of the electron density on N-benzoyl-L-pheylalanine and its palladium(II) complexes are carried out using the quantum theory of atoms in molecules (QTAIM) at the M06/6-31G( d ) theoretical level. The topological parameters derived from the Bader theory are also analyzed; these are characteristics of Pd bond critical points and ring critical points. The calculated structural parameters are the highest occupied molecular orbital energy ( E HOMO), the lowest unoccupied molecular orbital energy ( E LUMO), the hardness (h), the softness ( S ), the absolute electronegativity (c), the electrophilicity index (w), and the fractions of electrons transferred (D N ) from ethylenediamine, 2,2¢-bipyridine and 1,10-phenanthroline complexes to N-benzoyl-L-pheylalanine. The numerous correlations and dependences between the energy terms of the symmetry adapted perturbation theory approach, geometrical, topological, and energy parameters are detected and described.
