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

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.

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

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.
