摘要：

Bridging the gap! [MnIII 6O3(saO) 6(OCH3)6Ln2(CH3OH) 4(H2O)2] (Ln=La (1), Tb (2), saOH 2=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). © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
