Abstract

Schiff bases are among the widely used ligands due
to their structural and biological properties and their importance in our
practical life is increasing day by day. In this work, a Schiff base ligand                                                        
[5-methoxysalicylidene-o-aminophenol
(LH)] was synthesized from the reaction of                                                                         5-methoxysalicylaldehyde
and o-aminophenol, a salicylaldehyde
derivative. With using this ligand, complexes were prepared from Co⁺², Ni⁺²,
Cu⁺² ve Zn⁺²acetate salts. The Schiff base and complexes
were identified by using Elemental Analysis, FT-IR, ¹H-NMR, ¹³C-NMR,
UV-Vis, Magnetic Susceptibility and TGA as techniques.

Salisilaldehit Türevinden Schiff Bazı Ligandının Sentezi, Karakterizasyonu ve Bazı Geçiş Metal Komplekslerinin İncelenmesi

Abstract

Schiff bazları, yapısal ve biyolojik
özelliklerinden dolayı yaygın olarak kullanılan ligandlar arasında yer
almaktadır ve bunların pratik hayatımızdaki önemi de gün geçtikçe artmaktadır. Bu
çalışmada, bir salisilaldehit türevi olan 5-metoksisalisilaldehit ile o-aminofenol’ün reaksiyonundan bir
Schiff bazı ligandı                                              [5-metoksisalisiliden-o-aminofenol (LH)] sentezlendi. Bu ligand ile Co⁺², Ni⁺²,
Cu⁺² ve Zn⁺² asetat tuzlarından kompleksleri hazırlandı.
Schiff bazı ve kompleksleri elementel analiz, IR, ¹H-NMR, ¹³C-NMR,
UV-Vis, manyetik süsseptibilite ve TGA yöntemleri kullanılarak aydınlatıldı.
