摘要：

(Chemical Equation Presented) Forced to comply: The MnIII 6CrIII complex 1 is constructed from two trinuclear manganese triplesalen complexes and one [Cr(CN6)]3- ion, and possesses a spin ground state of St = 2 1/2. The threefold symmetry enforced by the triplesalen ligand precludes a complete cancellation of the single-site magnetic anisotropies and minimizes quantum tunneling of the magnetization. The analysis of the magnetic properties reveals that this complex is indeed a single-molecule magnet. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
