Synthesis, Characterization of Schiff Base Ligand from Salicylaldehyde Derivative and Investigation of Some Transition Metal Complexes

Öz

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.

Öz

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.
