Proton magnetic resonance studies of flavoquinone-metal complexes.
A detailed magnetic resonance investigation of the metal ion interaction with flavoquinones has been carried out with the purpose of obtaining the stoichiometry, stability and (sub) molecular structure of the complexes. The isotropic shifts of the paramagnetic chelates are analysed in terms of contact and pseudocontact contribution. It is shown that the flavoquinone-metal binding is mainly of σ-type regardless of the nature of the ion.
