[Mn III 6 O 3 Ln 2 ] Single‐Molecule Magnets: Increasing the Energy Barrier Above 100 K

Bridging the gap! [MnIII6O3(saO)6(OCH3)6Ln2(CH3OH)4(H2O)2] (Ln=La (1), Tb (2), saOH2=salicylaldoxime) were synthesized by a two-step self-assembly process from MnCl2, saOH2, and Ln(NO3)3 under basic conditions in methanol. Both complexes display single-molecule magnet (SMM) properties, with 2 exhibiting one of the highest known SMM energy gaps: 103 K (see figure).
