Abstract

   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.

SCHİFF BAZI KOMPLEKSLERİNİN SENTEZİ VE YAPILARININ İNCELENMESİ

Abstract

   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.
