Synthesis of Schiff Base Ligand Complex Compound and Investigation of Multiple Nuclear Fe(III)/Fe(II)/Fe(III) Metal Complex

Abstract

In this study, 5-aminoisophthalic acid (5-aminobenzene-1,3-dicarboxylic acid) was used as the starting material. The condensation reaction of 5-aminobenzene-1,3-dicarboxylic acid and ferrosecarboxyaldehyde gave [[(3,5-dicarboxyphenyl)imino]carbonyl]ferrocene. Then the four-saline ligand was obtained by condensation reaction with salicylaldehyde and ethylenediamine using the literature. Then the complex with anhydrous FeCl₃ was obtained and the resulting product was dimerized with NH₄OH to obtain Schiff base-containing ligand complex [Fe(salen)₂O]. By using the [Fe(salen)₂O] ligand complex with the Schiff base ligand complex we synthesized previously, multinuclear complexes with double oxygen bridges were obtained by using the -COOH groups. As a result, FT-IR, elemental analysis, ¹H NMR and magnetic susceptibility of ligands and complexes were investigated.

Schiff Bazı Ligand Kompleks Bileşiğinin Sentezi ve Multinükleer Fe(III)/Fe(II)/Fe(III) Geçiş Metal Kompleksinin İncelenmesi

Abstract

Bu çalışmada çıkış maddesi olarak 5-aminoisoftalik asit (5-Aminobenzen-1,3-dikarboksilik asit) kullanıldı. 5-Aminobenzen-1,3-dikarboksilik asit ile ferrosenkarboksialdehitin kondenzasyon reaksiyonundan [[(3,5-dikarboksifenil)imino]karbonil]ferrosen elde edildi. Sonra literatürden faydalanılarak salisilaldehit ve etilendiamin ile kondenzasyon reaksiyonu ile dört dişli salen ligandı elde edildi. Daha sonra susuz FeCl₃ ile kompleksi elde edildi ve sonuç ürün NH₄OH ile dimerleştirilerek Schiff bazı içerikli ligand kompleksimiz olan [Fe(salen)₂O] elde edildi. Daha önce sentezlediğimiz Schiff bazı ligand kompleksine [Fe(salen)₂O] ligand kompleksini ilave ederek -COOH gruplarının kullanılması ile çift oksijen köprülü multinükleer kompleksler elde edildi. Sonuç olarak, elde edilen ligandların ve komplekslerin FT-IR, ¹H NMR, elementel analizi ve manyetik süsseptibilite ölçümleri ile yapıları aydınlatıldı.
