The green complex of Mn(III) with desferrioxamine B has been prepared by air oxidation of Mn(II) in the presence of the ligand or by reaction of Mn(OH)3, or of MnO2, with the ligand. The resultant complex was purified by ion-exchange chromatography and shown by electrospray ionization mass spectrometry to be a 1:1 complex of Mn(III) with desferrioxamine B. A similar complex was prepared from the macrocyclic Tris hydroxamate desferrioxamine E. Mn(III) desferrioxamine B was not stable to… CONTINUE READING
