Abstract

In contrast to literature data, at millimolar iron and daunomycin (DN) concentrations no solitary Fe(DN)3 complexes are formed in appreciable amounts. The Mössbauer spectroscopic analysis revealed severe dependencies on temperature and on the metal ligand ratio. Two species can be discerned: exchange-coupled polynuclear aggregates, which are magnetically highly anisotropic and another superparamagnetic system, exhibiting much less magnetic anisotropy. The cooperative phenomena observed are attributed to stacking effects of daunomycin.
