For the nuclei included in our study, all chains of lanthanides begins as vibrational with R(4/2) near 2.0 and move towards rotational (R(4/2) [right arrow] 3.33) as neutron number increases.
The lanthanide ions like Pr being hard Lewis acids are more likely to bond with the oxygen atoms whereas transition metals like Cu are soft Lewis acids and are more likely to bond with the N atoms.
