When 2-naphthol is reacted with the diazonium salt of 5-amino-2,3-dihydrophthalazine-1,4-dione, (E)-5-((2-hydroxynaphthalen-yl)diazenyl))-2,3-dihydrophthalazine-1,4-dione is produced. Utilized microelemental analysis (C.H.N.O.) and spectroscopic studies (FTIR, UV-Vis, 1H and 13C-NMR, Mass) to determine the azo ligand. . Metal chelates of transition metals were prepared and analyzed using mass spectra, atomic absorption of flame, elemental analysis, infrared and UV-Vis spectral processes, as well as conductivity and magnetic measurements. The nature of the compounds produced has been studied following the mole ratio and continuous contrast methods, and Beer's law was followed during a concentration scope (1×10-4 - 3×10-4 mol/L). High molar absorptivity of compound solutions has been noticed. Analytical data showed that all the complexes are outo 1:2 metal-ligand ratio, except for the palladium complex, which has appeared at a 1:1 ratio. At the radix for physicochemical datum, an octahedral structure has been described for Ni(II) and Pt(IV) complexes and a square planar structure for the Pd(II) complex. Biological activity has been explored in connection to the effects of these complexes on blood lymphocyte division in the presence of PHA. The findings show that at different concentrations, Lpd causes a halt in cell division, which is more apparent. Furthermore, by generating a sustained mitotic block during the metaphase/anaphase, ligand (L) inhibited the proliferation of lymphocyte cell lines. Apart from that, using the chemicals produced to dye cotton fabric was a workable method. Dye stability under light and detergent conditions has been investigated.
