Synthesis and Characterization of Metal-Saccharin Complexes Containing N,N'-Bis(2-hydroxyethyl)piperazine
Öz
New complexes containing Co(II), Ni(II), Cu(II), and Zn(II) ions with N,N'-bis(2-hydroxyethyl)piperazine (bheppz) and saccharinate (sac) ligands were synthesized. The characterization of the complexes with the proposed formula [M₂(sac)₄(bheppz)(H₂O)₄] was performed using elemental analysis, magnetic susceptibility measurements, FT-IR spectroscopy, and thermal analysis methods. The FT-IR spectra displayed specific absorption bands corresponding to both the bheppz and saccharinate ligands. Thermal analysis indicated that the initial decomposition step involves the release of coordinated water molecules, followed by the breakdown of the bheppz ligand in subsequent stages. In the final stage, the decomposition of the saccharinate ligand leads to the formation of metal oxides.
