摘要：
The structure and properties of Cu(II) and Ni(II) complexes with Schiff bases-derivatives of ethylenediamine and salicylaldehyde or acetylacetone-are discussed based on the results of quantum-chemical calculations at the Hartree-Fock (ROHF/SBK) and density functional theory (B3LYP/SBK) levels. The natural bond orbital (NBO) method is used for studying the electronic structure of the complexes and assessing the contributions of donor-acceptor interactions. The nature of the organic ligand and the central ion turn out to impact the structure and properties of the complexes. The correlation between the metal-ligand bond energy and the electronic structure of the complexes is studied.
