Co(II), Ni(II), Cu(II) ve Zn(II) iyonları ile N,N'-bis(2-hidroksietil)piperazin (bheppz) ve sakkarinat (sac) ligandlarını içeren yeni kompleksler sentezlenmiştir. [M₂(sac)₄(bheppz)(H₂O)₄] formülüne sahip olduğu önerilen bu komplekslerin karakterizasyonu elementel analiz, manyetik duyarlılık ölçümleri, FT-IR spektroskopisi ve termal analiz yöntemleriyle yapılmıştır. FT-IR spektrumları, hem bheppz hem de sac ligandlarına özgü karakteristik absorpsiyon bantlarını göstermiştir. Termal analiz sonuçları, komplekslerin ilk bozunma evresinin koordine olan su moleküllerinin uzaklaşmasına karşılık geldiğini göstermektedir. Bunu takiben, bheppz ligandı ayrılmakta, son aşamada ise sac ligandının bozunmasıyla metal oksitler oluşmaktadır.

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.
