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.

[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.
