The preparation and properties of new complexes containing the biometals Fe
(III), Co(II) and Ni(II) coordinated to the anti-inflammatory drug Suprofen
are reported. The elemental analyses, together with the magnetic and therm
al behavior and electronic, IR and Raman spectra, indicated the following s
toichiometries for the latter two complexes: [M(Sup)(2)(H2O)(4)]. For the F
e(III) complex, the generation of a dinuclear species may be proposed on th
e basis of Fe-57 Mossbauer measurements.
