Importance of Axial Symmetry in Elucidating Lanthanide-Transition Metal Interactions
In this paper, we experimentally study and model the electron donating character of an axial diamagnetic Pd ion in four metalloligated lanthanide complexes of formula [PPh ][Ln{Pd(SAc) } ] (SAc = thioacetate, Ln = Tb, Dy, Ho, and Er). A global model encompassing inelastic neutron scattering, torque...

| Summary: | In this paper, we experimentally study and model the electron donating character of an axial diamagnetic Pd
ion in four metalloligated lanthanide complexes of formula [PPh
][Ln{Pd(SAc)
}
] (SAc
= thioacetate, Ln = Tb, Dy, Ho, and Er). A global model encompassing inelastic neutron scattering, torque magnetometry, and dc magnetometry allows to precisely determine the energy level structure of the complexes. Solid state nuclear magnetic resonance reveals a less donating character of Pd
compared to the previously reported isostructural Pt
-based complexes. Consequently, all complexes invariably show a lower crystal field strength compared to their Pt
-analogues. The dynamic properties show an enhanced single molecule magnet behavior due to the suppression of quantum tunneling, in agreement with our model. |
