Property‐Oriented Rational Design of Single‐Molecule Magnets: A <i>C</i>₃‐Symmetric Mn₆Cr Complex based on Three Molecular Building Blocks with a Spin Ground State of <i>S</i>_t=21/2

Abstract

Forced to comply: The MnIII6CrIII complex 1 is constructed from two trinuclear manganese triplesalen complexes and one [Cr(CN6)]3− ion, and possesses a spin ground state of St=21/2. 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.
