Abstract

The synthesis and characterisation of a large family of trimetallic [MnIII3] Single-Molecule Magnets is presented. The complexes reported can be divided into three categories with general formulae (type 1) [MnIII3O(R-sao)3(X)(sol)3-4] (where R = H, Me, tBu; X = O2CR (R = H, Me, Ph etc); sol = py and/or H2O), (type 2) [MnIII3O(R-sao)3(X)(sol)3-5] (where R = Me, Et, Ph, tBu; X = O2CR (R = H, Me, Ph etc); sol = MeOH, EtOH and/or H2O), and (type 3) [MnIII3O(R-sao)3(sol)3(XO4)] (where R = H, Et, Ph, naphth; sol = py, MeOH, β-pic, Et-py, tBu-py; X = Cl, Re). We show that deliberate structural distortions of the molecule can be used to tune the observed magnetic properties. In the crystals the ferromagnetic triangles are involved in extensive inter-molecular H-bonding which is clearly manifested in the magnetic behaviour, producing exchange-biased SMMs. These interactions can be removed by ligand replacement to give “simpler” SMMs.
