摘要
The electronic structure of 3d-metals bis and tris-beta-diketonates was studied by methods of UP spectroscopy and quantum chemistry in ab initio, X alpha-DV and INDO approximations. According to PE data, the covalent interaction metal-legand is realized, on the whole, by n-electrons, and IE1 in all compounds caused by d-electrons. The X alpha-DV calculations give a good agreement with experimental picture of interaction of metal AOs and ligand orbitals. Ab initio calculations showed the main role of high sigma-orbitals in covalent interaction. All quantum chemical methods overstate multiplet splitting of ligand levels caused by overestimation of a delocalization factor of d-electrons. (C) 1998 Elsevier Science B.V. All rights reserved.
