Yeni bir oksim içeren Schiff bazı ligandı ve onun Cu (II), Ni (II), Zn (II) kompleksleri sentezlendi. Bileşiklerin karakterizasyonunda TGA, FT-IR, 1H NMR, SEM, element analiz, iletkenlik ölçümleri, manyetik duyarlılık ve UV-görünür spektrofotometrik çalışmalar kullanılmıştır. Metal kompleksleri, DMSO ve DMF' de çözünmüştür. UV-Görünür spektrofotometrik analiz, manyetik süsseptibilite, 1H NMR spektrumları tüm komplekslerin dört koordineli geometride olduğunu göstermiştir. Sentezlenen Cu (II), Ni (II) ve Zn (II) komplekslerinin Termogravimetrik analizleri 900 ºC'de yapıldı ve termal bozunmaları iki aşamada gerçekleşmiştir. Schiff bazı komplekslerinin son termal bozuma kalıntısı metal oksitler olmuştur.

Synthesis, Morphology, Spectral Characterization and Thermal Behaviors of Transition Metal Complexes Containing Oxime-Imine Group

Öz

A new oxime-containing Schiff base ligand and its Cu(II), Ni(II), Zn(II) complexes have been synthesized. The structure of the ligand was identified by elemental analysis, UV-vis, FT-IR, 1H NMR and 13C NMR spectra. The synthesized complexes were characterized by FT-IR, SEM, TGA, elemental analysis, electronic spectra and magnetic susceptibility measurements. The Zinc(II) complex was also characterized by 1H NMR spectra. Elemental analysis data of the metal complexes indicated that the metal: ligand ratio of the metal complex is 1:1. The magnetic susceptibility measurements and spectral data showed square-planar geometry for Cu(II) complex and tetrahedral geometry for Ni(II) complex.
