Mononuclear and binuclear complexes of mefenamic acid with Fe(III) ions of formulae Na[Fe(C15H14O2N)4] and Fe2Cl(C15N14O2N)5 were obtained in the solid phase. Characterization of the complexes was performed by elemental analysis and visible, IR, 1H and 13C NMR spectroscopy and possible structures are proposed.
