Bakır(II) iyonunun 5,7-dihidroksiflavon ve sübstitue 2,2’-bipiridin ile yeni bir karışık ligand kompleksi

Öz

Bu çalışmada 5,7-dihidroksiflavon (chrysin, chr) ve 4,4′-di-ter-bütil-2,2′-bipiridin (4,4’-dtbbpy) ligandları kullanılarak Cu(II) iyonunun yeni bir karışık ligand-bakır(II) koordinasyon bileşiği elde edildi. Sentezlenen bu koordinasyon bileşiğinin yapısı, elementel analiz, iletkenlik, manyetik süsseptibilite, kütle spektrometrisi ve Infrared (IR) spektroskopisi yöntemleriyle aydınlatıldı. Ayrıca TGA/DSC analizi ile yapısı desteklendi ve termal özellikleri araştırıldı. Elde edilen analiz verilerinden sentezlenen bileşikte, Cu(II) iyonu:chr-H:4,4’-dtbbpy oranının 1:1:1 olduğu ve koordinasyon küresi içerisinde ClO4- iyonunun bulunduğu nötral bir kompleks elde edildiği saptandı. Sonuç olarak sentezlenen koordinasyon bileşiği için [Cu(chr-H)(ClO4)(4,4’-dtbbpy)] formülü önerildi.

A new mixed ligand complex of copper(II) Ion with 5,7-dihydroxyflavone and substituted 2,2'-bipyridine

Öz

In this study, a new mixed ligand-copper(II) coordination compound of Cu(II) ion was obtained by using 5,7-dihydroxyflavone (chrysin, chr) and 4,4′-di-tert-butyl-2,2′-bipyridine (4,4’-dtbbpy) ligands. The structure of this synthesized coordination compound was elucidated by elemental analysis, conductivity, magnetic susceptibility, mass spectrometry and Infrared (IR) spectroscopy methods. In addition, its structure was supported by TGA/DSC analysis and its thermal properties were investigated. From the analysis data obtained, in the synthesized compound it was determined that the ratio of Cu(II) ion:chr-H: 4,4’-dtbbpy was 1:1:1 and a neutral complex was obtained with ClO4- ion in the coordination sphere. As a result, the formula [Cu(chr-H)(ClO4)(4,4'-dtbbpy)] was proposed for the synthesized coordination compound.
