the pseudo-octahedral [MnL(H2O)2] is obtained. These manganese (II) species absorb approximately 0.5 mol O2 per mol of Mn to form dimeric di-µ-oxo manganese (IV) complexes [MnL(O)}2], but this reaction in NN-dimethylformamide is surprisingly much faster for the complex [MnL(H2O)2] than for the planar species. In addition some manganese(III) complexes [MnL(H2O)] ClO4 have been obtained.
