pi-Electron Communication Through the Metal Valence Shell –W, Mo and Fe Complexes Containing Maleimidato Moiety
Marcin Palusiak · Polish Journal of Chemistry · 2007
The characterization of carbonyl-metal and maleimidato-metal bonding has been performed using the topological analysis of electron distribution function estimated for molecules of (η 5 -C 5 H 5 )M(CO) 3 (η 1 -N-maleimidato) (M = W, Mo) and (η 5 -C 5 H 5 )Fe(CO) 2 (η 1 -N-maleimidato). The Atoms in Molecules (AIM) approach has been applied for characterization of a and it-components of the metal-ligand bonds. Then-electron communication between trans-placed ligands is present in W and Mo derivatives. The ellipticity parameter is suggested to be a useful and highly sensitive parameter in the analysis of the metal-ligand bonding.
