Piperazin İçeren Polimerik Co(II), Ni(II), Zn(II) ve Cd(II) Sakkarin Komplekslerinin Sentezi, Spektroskopik ve Termik Özellikleri

[M(sac)2(H2O)4] 2H2O (M= Co(II), Ni(II), Zn(II) ve Cd(II), sac=sakkarinat anyonu)’nun piperazin(ppz) ile reaksiyonu sonucu yeni kompleksler sentezlendi. Kompleksler elementel analiz, manyetik ölçümler, FT-IR spektroskopisi ve termik analiz çalışmalarıyla karakterize edildi. Tüm komplekslerin IR spektrumu ppz ve sac ligantlarının tipik absorpsiyon bantlarını göstermektedir. Komplekslerin termik analiz çalışmalarında, ilk basamak yapıdan akua ligandının uzaklaşmasına karşılık gelir. Ardından takip eden basamaklarda ppz ligandı uzaklaşır, son olarak da sac uzaklaşarak karşılık gelen metal oksitler ele geçer.

Synthesis, Spectroscopic and Thermal Characteristics of Polymeric Co(II), Ni(II), Zn(II) and Cd(II) Saccharin Complexes Containing Piperazine

The reaction of [M(sac)2(H2O)4] 2H2O (M= Co(II), Ni(II), Zn(II) and Cd(II); sac = saccharinate anion) with piperazine(ppz) results in the formation of the new complexes. The complexes have been characterized by elemental analyses, magnetic measurements, FT-IR spectroscopy and thermal analysis. The IR spectrum of all the complexes displays typical absorption bands of ppz and sac ligands. In the thermal analysis studies of the complexes, the first decomposition stage corresponds to the decomposition of aqua ligand. In the following stages the decomposition of ppz ligand takes place and the sac decomposes at the final stage of the decomposition to give the metal oxides.
