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.

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.
