Fundamental Bonding Concepts of Inorganic Chemistry Revisited

The bonding situation in a variety of systems from inorganic chemistry is analyzed by application of a variety of bond analysis methods from real space, orbital space und energy space - a complementary bonding analysis. Fundamental bonding concepts such as bond polarization, resonance, hyperconjugative interactions and hypervalency are analyzed by this approach. It is shown that a complementary bonding analysis is a powerful tool to tackle complex bonding situations. The analysis is based on theoretically obtained wavefunctions and on the novel approach of X-ray wavefunction refinement.
