The influence of metal cations such as Zn2+, Fe2+, Mn2+, Ni2+, Co2+, Hg2+ and Cu2+ on the spectroscopic properties of the ligands, the starting material dinitrile and MgPz were investigated in acetonitrile-chloroform solution (1/1) by means of absorption spectrometry. Absorption spectra showed isosbestic points in the spectrophotometric titration of Cu2+ and Hg2+ with MgPz ligand. The results of spectrophotometric titration experiments disclosed the complex stability constant of the novel ligand, MgPz with Cu2+ and Hg2+ cations.eninfo:eu-repo/semantics/closedAccessabsorption spectroscopyCrown ethermetal cationporphyrazinestability constantabsorption spectroscopyCrown ethermetal cationporphyrazinestability constantArticle14111110.3233/MGC-1401482-s2.0-84915750804Q4WOS:000345980500001Q4
