Title: Synthesis and spectral study of new azo dye and its iron complexes derived from 2-naphthol and 2-amino-3-hydroxypyridine

An azodye C{sub 5}H{sub 12}N{sub 3}O{sub 2} [LH] is synthesised by coupling diazotised 2-amino-3-hydroxy pyridine with 2-naphthol in ice cold condition. The Fe(II)and Fe(III) complexes were prepared by mixing ethanol solution of metal salt and azodye in 1:2 molar ratio. The dye and metal complexes are structurally characterised by elemental analysis, molar conductance, magnetic susceptibility measurements and spectral techniques like IR, UV-Vis, and Mössbauer analysis. Analytical data suggests the stoichiometry as [FeL{sub 2}Cl(H{sub 2}O)] for Fe(III) complex and [FeL{sub 2}(H{sub 2}O)] for Fe(II) complex. The IR spectral data suggests that [L{sup −}] is acting as a uninegative bidentate ligand. A high spin octahedral geometry is tentatively proposed for both the complexes with respect to the above studies.
