Abstract

Nickel complexes, especially with Schiff bases gain potential interest in various areas such as catalysis, luminescent probes in analytical chemistry, dye and polymer industry, food industry, magneto-structural chemistry, agrochemistry, biological fields and several miscellaneous applications. There are numerous reports on the biological activities of Schiff base ligands and their metal complexes, including their use for DNA cleavage, enzyme modeling, and as antimicrobial, antifungal and antitumor agents [1]. In our research, new nickel complexes were synthesized with α-glyoximes, such as [Ni(Me-propyl-GlyoxH)2(imidazole)2], [Ni(Me-pentyl-GlyoxH)2(diisopropyl-amine)2], [Ni((4-benzyl-2-hydroxy-phenyl)-Me-GlyoxH)2], where GlyoxH = mono deprotonated glyoxime, and with Schiff bases, such as [Ni(3-heptanone)2A], [Ni(propiophenone)2A], A = ethylenediamine (en), 1,2-, 1,3-propylenediamine (1,2-pn, 1,3-pn), o-phenylene-diamine (o-fen). The Schiff bases were obtained with a simple condensation reaction between 3- heptanone or propiophenone and the corresponding diamines. The molecular structure of our products was investigated by IR, UV–VIS spectroscopy, mass spectrometry (MS), thermoanalytical measurements (TG-DTG-DTA), and powder XRD. The biological activity was studied for a few bacteria, however, these complexes have shown no antibacterial activity so far.
