| الوصف: | We are reporting the synthesis and structural characterization of a new family of butterfly complexes with formula [Co 2 III Ln 2 III −(μ 3 −(OR)) 2 ] where −OR is an alcohol‐amine type ligand, in this case N‐methyldiethanolamine (H 2 mdea) with Ln=Tb, Dy, Ho, Er and Yb. This new family adds to the previously reported one, where the alcohol‐amine ligand is triethanolamine (H 3 tea), and allows a one‐to‐one comparison between them. From a combined experimental study, that included DC and AC magnetometry as well as HF‐EPR measurements, and a theoretical approach based on Broken‐Symmetry DFT and CASSCF‐SA‐SOC ab‐initio computations, we discuss the single molecule magnet (SMM) performance in these complexes. We focus in a few key structural parameters that correlate with the magnetization relaxation behaviour observed along the different explored lanthanide ions. |
