Metal(II) 4‐Etilbenzoatların Karışık‐Ligand Komplekslerinin Sentezi ve Karakterizasyonu

Bu çalışmada Cu(II), Co(II), Ni(II), Pb(II), Mn(II) ve Zn(II) 4‐etilbenzoatların nikotinamid/N,N‐ dietilnikotinamid ligandları ile kompleksleri sentezlenmiştir. Komplekslerin yapılarını aydınlatmak için elementel analiz, IR, UV‐Vis, 1H ve 13C NMR spektroskopisi yöntemleri kullanılmıştır. Sentezlenen komplekslerin termik özelliklerine bakıldığında su ligandı içeren komplekslerde ilk bozunma basamağında su molekülleri yapıdan ayrılmaktadır. Devam eden basamaklarda organik ligandlar tamamen veya kısmen bozunmaya uğramaktadır. Komplekslerin nihai termal bozunma ürünleri uygun gelen metal veya metal oksittir.

Synthesis and Characterization of Mix‐Ligand Complexes of Metal(II) 4‐ Ethylbenzoates

In this study, metal complexes of 4‐ethylbenzoate containing nicotinamide and N,N diethylnicotinamide were synthesized. Elemental analysis, IR, UV‐VIS, 1H and 13C NMR Spectroscopy methods were used for the elucidation of the structures of complexes. The thermal behaviors of complexes were determined by simultaneous thermal analysis techniques. The thermal decomposition of hydrated complexes started with dehydration process. Organic ligands were partially or fully degraded at continued steps. The final products of thermal decomposition have been determined as metal or metal oxides.
