Abstract:
We report a supramolecular approach to mixed-valent Mn coordination clusters that demonstrates how
halide ions can be applied to in
fl
uence the assembly of distinct tetranuclear building units to produce a
number of related Mn coordination clusters with dense core structures that derive from a cuboctahedral
arrangement of Mn ions. In all compounds the alignment of the Jahn
–
Teller axes of the Mn
III
centers
coincides with the positions of the stabilizing chloride ligands. Thus, the relative chloride concentrations
in the reaction mixtures allow us to modify the symmetry and magnetic anisotropy of this basic core
structures resulting in isotropic polynuclear high-spin complexes at high Cl
−
concentrations and Single-
Molecule Magnets at lower relative Cl
−
concentrations
