| Abstract The New bidentate azo dye ligand 4-[(6-purinyl)azo]1-naphthol (PAN) was prepared by reacting a diazonium salt solution of 6-amino purine with 1-naphthol in alkaline solution . The ligand and its complexes with metal ions; Fe(Ⅱ), Co )Ⅱ(, Ni (Ⅱ)and Cu )Ⅱ(were prepared and characterized by infra-red ( FT.IR) , Uv-visible spectroscopy , atomic absorption ,(C.H.N) analysis , Magnetic susceptibility and molar conductivity measurements . All complexes were found to have a general formula [M(PAN)2(H2O)2]Cl2 . The complexes with 1:2 (M:L) showed octahedral geometry around metal ions .The molar conductance data reveal that complexes are electrolytes 2:1, IR spectra show that the ligand is coordinated to the metal ions in a 4-(6-purine azo )-1-naphthol through the azo N and purine heterocyclic N . | ||
