Abstract:
A new family of hexametallic [Mn(III)₆] Single-Molecule Magnets with general formula [Mn₆O₂(R-sao)₆(X)₂(MeOH)₄₋₆] (R= H, Me, Et or Ph; X = O₂PHPh or O₂P(Ph)₂) have been synthesised and characterised. The molecules are new members of the [Mn₆] family of SMMs in which the carboxylate ligands have been replaced with phenyl- and diphenylphosphinate. The magnetic cores remain largely unaltered meaning that structural distortions of the Mn-N-O-Mn torsion angles in the [Mn₃O] subunits can be used to tune the magnetic properties, switching pairwise exchange interactions from antiferromagnetic to ferromagnetic. The results suggest that the Mn₆ building block, be it ferro- or antiferromagnetically coupled, could be an important building block for the formation of novel, functional 0-3D materials.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
