1,5-Bis(2-carboxyphenyl)-3-ferrocenylformazan (BFF) has been synthesized by the coupling reaction of the diazonium salt of 2-aminobenzoic acid and ferrocenealdehyde-2-carboxyphenylhydrazone (FFH). FFH was obtained from the condensation reaction of ferrocenealdehyde with 2-carboxyphenylhydrazine. The Cu(II) and Co(III) complexes of BFF have been isolated. The structures of the formazan and its complexes were confirmed on the basis of elemental analysis, proton and C-13 NMR, IR and UV-Vis spectral data.
