Absztrakt (kivonat)
In our research project new iron(II) complexes were synthesized with azomethines, such as [Fe(1,4-dibromo-2,3-butane-GlyoxH)2(3-HO-aniline)2], [Fe(1,4-dibromo-2,3-butaneGlyoxH)2(2-amino-pyrimidine)2], [Fe(4-benzyl-2-HO-propiophenone-GlyoxH)2], [Fe(5- methyl-2-hexanone)2(en)], [Fe(5-methyl-2-hexanone)2(1,2-pn)], [Fe(5-methyl-2-hexanone)2 (1,3-pn)], [Fe(5-methyl-2-hexanone)2(o-fen)], [Fe(2,4,5-trimethoxy-acetophenone-SC)2], [Fe(2,4,5-trimethoxy-acetophenone-TSC)2], [Fe(5-methyl-2-hexanone-SC)2], [Fe(5-methyl-2- hexanone-TSC)2], [Fe(Me-Pr-Glyox)3(BOH)2], [Fe(Me-Pr-Glyox)3(BOMe)2], [Fe(Me-i-BuGlyox)3(BOH)2], [Fe(Me-i-Bu-Glyox)3(BOMe)2], [Fe(Me-i-Bu-Glyox)3(BO-n-propyl)2] (en = ethylenedianine, pn = propylenediamine, fen = phenylenediamine, SC = semicarbazone, TSC = thiosemicarbazone), by reacting iron(II)-chloride with different glyoximes, Schiff-bases, semi- or thiosemicarbazones in suitable solvent. The Schiff-bases were obtained with the condensation of 5-methyl-2-hexanone, with diamines. The semi- or thiosemicarbazones were prepared by the condensation of 2,4,5-trimethoxy-acetophenone or 5-methyl-2-hexanone with semicarbazide or thiosemicarbazide. We analyzed their physicochemical properties using mass spectrometry, infrared-, NMR-, UV–VIS-, Mössbauer-spectroscopy, powder-XRD and thermal analysis (TG, DTG and DTA). The biological activity of complexes, especially their antibacterial activity was also explored. The importance of this class of compounds is gained in biochemistry, since some of them act as antibacterial agents and potential anticancer drugs. Furthermore, some members can play role as catalysts in organic chemistry transformations [1–2].
