X-ray photoelectron study of electron density distribution in palladium(II) β-diketonate complexes

Abstract

This work is devoted to experimental (X-ray photoelectron) and theoretical investigations of electron density distribution in Pd(II) β-diketonate complexes. Data about the electronic structure (effective charges, core level energies) of the compounds are compared with their thermodynamic parameters (thermal stability, vaporization enthalpy). In molecular crystals of Pd(II) β-diketonates, the volatility of the complexes and vaporization enthalpy ΔH T0 depend not only on van der Waals interactions, but also on electrostatic interactions of molecules in crystal. © 2007 Springer Science+Business Media, Inc.
