The Synthesis of Melamine Cored Schiff Bases and Investigation of Heteronuclear Metal Complexes

Abstract

In this study, 2,4,6-triamino-s-triazine (melamine) is the starting material. The condensation reaction of melamine and 4-hydroxybenzaldehyde resulted in the formation of the monopodal Schiff base. An oxygen-bridged monopodal complex of [(Fe(III)Salophen)Cl] ligand complex with monopodal Schiff base ligand was then obtained. Tripodal Schiff base ligand was obtained by condensing 2-hydroxybenzaldehyde with a monopodal complex and this ligand in some transition metal complexes were synthesized. As a result, the ligand and complexes of this ligand were isolated, as well as elemental analyses, FT-IR, 1H-NMR, TGA and magnetic susceptibility measurements of the obtained compounds were taken to elucidate their structures.

Melamin Merkezli Schiff Bazlarının Sentezi ve Heteronükleer Metal Komplekslerinin İncelenmesi

Abstract

Bu çalışmada başlangıç materyali olarak 2,4,6-triamino-s-triazin (melamin) kullanıldı. Melamin ve 4-hidroksibenzaldehitin kondenzayon reaksiyonu monopodal Schiff bazının oluşmasıyla sonuçlandı. Daha sonra monopodal Schiff bazı ligandı ile [(Fe(III)Salophen)Cl] ligand kompleksi bir oksijen köprülü monopodal kompleks elde edildi. Monopodal kompleks ile 2-hidroksibenzaldehitin kondenzayonu ile tripodal Schiff baz ligandı elde edilerek bu ligandın bazı geçiş metal kompleksleri sentezlendi. Sonuç olarak, ligandı ve bu ligandın kompleksleri izole edildi, ayrıca elde edilen bileşiklerin elementel analizleri, FT-IR, 1H-NMR, TGA ve manyetik süssebtibilite ölçümleri alınarak yapıları aydınlatıldı.
