Özet
Nickel(II) and cupper(II) complexes of HL are synthesized, HL - the Schiff base derived from 1-naphtylamin and 2-hydroxynaphthalin-l-carbaldehyde. Cupper(II) and zinc(II) complexes of L? are synthesized, L? - the Schiff base derived from 1,4-diaminobuthane and 4-methoxy benzaldehyde. 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 for the existence of the mononuclear compounds corresponding to a stoichiometry of MII : L (1 : 2) type. Furthermore, the conductometric determination of complexation constant, Ke, of AgNO3, ZnCl2 and Cu(NO3)2 in 80% dioxan-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.
