Özet
The nickel(II), copper(II), and zinc(II) complexes with Schiff bases derived from 1-naphthylamine and 2-hydroxynaphthaline-1-carbaldehyde (HL) or 1,4-diaminobutane and 4-methoxy benzaldehyde (L?) have been prepared. The complexes have been characterized by elemental analysis, magnetic measurements, conductance measurements, 1H NMR, UV, visible and IR-spectra. Analytical data and conductance spectral and magnetic studies provide evidence of the existence of mononuclear compounds corresponding to a stoichiometry of the MII:L (1:2) type. Furthermore, the conductometric determination of the complexation constant, Ke, of AgNO3, ZnCl2, and Cu(NO3)2 in 80% dioxane-water in the presence of HL and L? Schiff bases has been investigated. A small complexation constant value was found for the Cu(NO3)2 with both HL and L? Schiff base ligands.
