Abstract (2. Language): 
In this study, dinuclear iron(II) and manganese(II) complexes were synthesized using two different ligands containing oxime group. These new complexes have been characterized by elemental analyses, ICP-OES, FT-IR spectra, TG, magnetic susceptibility and conductivity measurements. The results suggest that the dinuclear complexes of H2L1 and H4L2 have a metal:ligand ratio of 2:2 and 2:1, respectively. Furthermore complexes were each tested both for their ability to catalyse the disproportionation of hydrogen peroxide in the presence of the added base imidazole and oxidation reaction of 3,5-di-tert-butylcatechol to the 3,5-di-tert-butylquinone presence of O2. It was found that all complexes exhibited good both catalase and catecholase activity.
Abstract (Original Language): 
Bu çalışmada, oksim grubu içeren iki farklı ligand kullanılarak dinükleer demir(II) ve mangan(II) kompleksleri sentezlenmiştir. Bu yeni kompleksler elemental analiz, ICP-OES, FT-IR spektroskopisi, TG, manyetik duyarlılık ve iletkenlik ölçümleriyle karakterize edilmiştir. Sonuçlar H L 1 ve H4L2 ' n in dinükleer komplekslerinin sırasıyla 2:2 ve 2:1 metal:ligand oranına sahip olduklarını göstermektedir. Ayrıca her bir kompleksin imidazol varlığında hidrojen peroksitin disproporsiyonu reaksiyonundaki ve O2 varlığında 3,5-di-t-bütilkatekolün 3,5-di-t-bütilkinona yükseltgenmesi reaksiyonundaki katalitik etkinliği incelenmiştir. Tüm komplekslerin iyi katalaz ve katekolaz aktiviteye sahip oldukları bulunmuştur.
