Effect of the substituents on the spin coupling between iminosemiquinone pi-radicals mediated by diamagnetic metal ions: l.s. Co(III) vs Ga(III).
Exchange coupling between the radical iminosemiquinone ligands changes from ferromagnetic to antiferromagnetic in l.s. Co(III) complexes, whereas the same coupling in Ga(III) complexes is always antiferromagnetic.
