Several mononuclear Ni(II) and Co(II) complexes of bidentate salicylaldimines (LxH), derived from 3,5-di-tert-butyl-2-hydroxybenzaldehyde with biologically active amines [1-(3-aminopropyl)imidazole, 4-(3-aminopropyl)morpholine, 1-(3-aminopropyl)-2-pyrrolidinone], have been synthesized. The complexes have been characterized by FT-IR, UV-vis, MS, 1H-NMR and 13C-NMR, magnetic susceptibility measurements, thermogravimetric analyses (TGA) and electrochemistry. As a result of thermal analyses, Co(L3)2 has highest thermal stability of the complexes, whereas the smallest one has Ni(L2)2. Electrochemical experiments indicated that Ni(II) and Co(II) complexes show quasi reversible reduction to Ni(I) and Co(I), respectively.
