In this work we evaluated the bonding nature and electronic properties of a series of metal-cyclopentadienyl MCp 3 complexes. The Morokuma-Ziegler analysis show a covalent character increase of the metal-ligand bond in the following order: transition-metals > actinide > lanthanide containing molecules. NBO and frequency analysis shows a similar behavior. TD-DFT calculation shows a red shift for the a″→ a′ transition, which is common to all the complexes. The NICS zz values and ELF analysis show a ring electron delocalization change due to a combined effect between the more external metal orbitals 'nd' and the interaction with the hydrogens of the neighboring ring.
