Abstract. Metal complexes of Schiff base ligand (5-bromo-3-methoxysalicyliden-p-iminoacetophenone oxime) derived from 5-bromo-3-methoxsalicylaldehyde and p-aminoacetophenoneoxime is reported. Schiff base was found to be bidentate ligand involving the imino nitrogen and carboxyl oxygen atoms in the complexes. Metal to ligand ratio were found to be 1:2 for all of the complexes. Co(II), Ni(II), and Zn(II) complexes have been found tetrahedral geometry and Cu(II) complex has been found four coordinated geometry. The complexes are found to have the formulae [M(L)2]. The compounds obtained have been characterized by their elemental analyses, IR, 1H-NMR, 13C-NMR, UV spectra, magnetic susceptibility and thermogravimetric analyses (TGA).

Keywords: Schiff base, transition metal complexes

 

Özet. Bu çalışmada, 5-brom-3-metoksi salisilaldehit ve p-aminoasetofenon oksimden türetilmiş Schiff bazı ligandı (5-brom-3-metoksisalisiliden-p-iminoasetofenon oksim) nın metal kompleksleri rapor edildi. Bütün komplekslerde Schiff bazlarının metal iyonuna imin azotu ve fenolik oksijeninden bağlanarak iki dişli şelat olarak davrandığı ve yine bütün komplekslerde M:L oranının 1:2 olduğu görüldü. Co+2, Ni+2 ve Zn+2 komplekslerinin tetrahedral ve Cu+2 kompleksinin ise dört koordinasyonlu yapıya sahip olduğu belirlendi. Komplekslerin [M(L)2] formülüne sahip oldukları bulunmuştur. Elde edilen bileşiklerin yapıları, elementel analiz, IR, 1H-NMR, 13C-NMR, Uv, manyetik süsseptibilite ve termogravimetrik analiz ile karakterize edilmiştir.
