SYNTHESIS AND CHARACTERIZATION OF TRANSITION METAL COMPLEXES OF NEW PROTON TRANSFER SALT OF 1,4-PYRAZINE-2,3-DICARBOXYLIC ACID

1,4-PİRAZİN-2,3-DİKARBOKSİLİK ASİTİN YENİ PROTON TRANSFER TUZU İLE GEÇİŞ METAL KOMPLEKSLERİNİN SENTEZİ VE KARAKTERİZASYONU

Abstract

In this study, the proton tansfer salt (H2Etppz)(pyzdc)(1) was synthesized from the reaction of 1,4-pyrazine-2,3-dicarboxylic acid (H2pyzdc) with 2-(piperazine-1-yl)ethanol (H2Etppz). The proton transfer salt (1) was characterized using elemental analysis, 1H and 13C NMR, FTIR, UV-Vis techniques. The Mn(II) (2), Co(II) (3), Cu(II) (4) and Zn(II) (5) complexes of proton transfer salt (1) were synthesized. The structures of the complexes; have been suggested according to results of the FTIR, UV-Vis, ICP-OES and magnetic susceptibility methods

Özet

Bu çalışmada 1,4-pirazin-2,3-dikarboksilik asit (H2pyzdc) ve 2-(piperazin-1-il)etanol (H2Etppz) bileşiklerinin tepkimesinden proton transfer tuzu (H2Etppz)(pyzdc)(1) sentezlendi. Proton transfer tuzunun (1) yapısı; elementel analiz, 1H ve 13C NMR, FTIR ve UV-Vis yöntemlerinden yararlanılarak aydınlatıldı. Proton transfer tuzunun (1) Mn(II) (2), Co(II) (3), Cu(II) (4) ve Zn(II) (5) kompleksleri elde edildi. Komplekslerin yapıları; FTIR, UV-Vis, ICP-OES ve manyetik duyarlılık yöntemleri sonuçlarına göre önerildi.
