Özet
Four new metal complexes of Cu(II), Ni(II), Zn(II) and Co(III) with Schiff base derived from 4-methoxybenzaldehyde and 1,2-bis(p-aminophenoxy)ethane have been prepared and characterized by magnetic susceptibility, conductance measurements, elemental analyses, UV-Vis, H-1 NMR and IR spectra studies. The magnetic and spectroscopic data indicate an octahedral geometry for the six-coordinate complexes. The ligand was used for complexation studies. Stability constants were measured by means of a conductometric method. Furthermore, the stability constants for complexation between ZnCl2, Cu(NO3)(2) and AgNO3 salts and ligand (L) in 80% dioxane-water and pure methanol were determined from conductance measurements. In 80% dioxane-water, the stability constants (log Ke) increase inversely with the crystal radii in the order Ag(I) < Zn(II) < Cu(II).
