Systematic investigation into the influence of base and substituents on the coordination chemistry of MnIII and MnIII/II salicylate complexes

Asystematic investigation into the coordination chemistry ofMnIII salicylates is presented revealing the influence on the shape and dimensionality of the final products of base, the presence or absence of co-ligands and the substituents on the salicylates. We report the synthesis, structures, characterisation and magnetic properties of seven compounds, (NHEt3) [MnIII(3-MeOsal)2(MeOH)(H2O)] (1), [NaMnIII(3MeO-sal)2(MeOH)2] (2), [NaMnIII(sal)2(H2O)(MeOH)] * (MeOH) (3), [KMnIII(sal)2(H2O)(MeOH)] * (MeOH) (4), [MnIIMnIII2(3-MeOsal)4(py)6(H2O)2] * 4H2O, (5), [MnIIMnIII2 (3-MeO sal)4(py)4 (H2O)4] * 4MeOH, (6) and [MnIIMnIII2 (3-MeO-sal)4(2,20-bipy)(H2O)3(MeOH)2] * 3MeOH (7). Magnetic studies show the presence of antiferromagnetic interactions between the paramagnetic centres in all cases
