ELECTRONIC ASPECTS OF FUNGICIDAL ACTIVITY IN TRANSITION METAL DITHIOCARBAMATE COMPLEXES

In this study of the fungicidal activity of a series of transition metal ion dithiocarbamates in relation to their electronic structure, a model is presented to interpret the biological activity of these complexes, namely the ability of the complex to fit into a receptor site and its ability to undergo reversible redox reactions at suitable potentials. It is shown that in the case of the iron(III) dithiocarbamate complexes these properties are manifested in the spin state of the iron ion.
