Abstract
In this work, the ligand was obtained from the reaction of diazonium salt of naphthyl
amine with 1-amino-2-naphtol-4-sulfonic acid. The bidentate ligand type (NO) donar atoms
was reacted with 1,10-phenanthroline and matel salt in a 1:1:1 mole ratio to give the
complexes, using NaOH as a base. Physical-chemical teqnichas were used to characteriz the
prepared compounds FT-IR,U.V-Vis, fluorescence and 1HNMR spectroscopy, atomic
absorption , chloride content along with conductivity and melting point measurements
.Finally, thermal analysis was used to confirm the presence of coordination H2O molecule in
the complexes structure. According to memtioned characterization methods, the general
formula proposed for CoII ZnII, CdII and HgII complexes is [M(L)(phen)(H2O)Cl].
