SYNTHESIS OF SCHIFF BASE COMPLEXES AND INVESTIGATION OF STRUCTURES

Öz

   Schiff base compounds are stable, readily synthesizable compounds. Besides, in many fields of chemistry having a wide use field in, engineering, medicine and pharmacy has increased the interest in these compounds and made them widely available in different fields. A new Schiff base ligand, 4-chlorophenylimino-4-methoxysalicylaldehyde was synthesized by the reaction of 4-Methoxysalicylaldehyde and 4-chloroaniline. The colored complexes were synthesized by adding of acetate salts of Co(II), Cu(II) ve Zn(II) to the solution of 4-chlorophenylimino-4-methoxysalicylaldehyde dissolved in methanol. The compounds obtained have been characterized by their elemental analyses, fourier transform infrared (FT-IR), nuclear magnetic resonance (¹H NMR), thermogravimetric analysis (TG/DTG), conductometric measurements and magnetic susceptibility.

Öz

   Schiff bazı bileşikleri kararlı, kolay sentezlenebilen bileşiklerdir. Bunun yanısıra, kimyanın pek çok alanında, mühendislik, tıp ve eczacılıkta alanında geniş kulanım alanlarına sahip olmaları bu bileşiklere olan ilgiyi artırmış, onları farklı alanlarda yaygın olarak kullanılabilir hale getirmiştir. 4-Metoksisalisilaldehit ve 4-kloranilin’in reaksiyonundan yeni bir Schiff bazı ligandı, 4-klorofenilimino-4-metoksisalisilaldehit sentezlendi. Metanollü ortamda çözülmüş, 4-klorofenilimino-4-metoksisalisilaldehit ligandına, metanolde çözülmüş olan Co(II), Cu(II) ve Zn(II) asetat tuzları ilave edilerek renkli kompleksler sentezlendi. Elde edilen bileşiklerin yapıları, İnfrared spektroskopisi (FT-IR), nükleer manyetik rezonans (¹H NMR), termogravimetrik analiz (TG/DTG), manyetik süsseptibilite, kondüktometrik ölçümleri ve elementel analiz yöntemleriyle ile karakterize edilmiştir.
