<p>U ovoj doktorskoj disertaciji proučavano je građenje kompleksa kobalta(II) sa hloridnim i bromidnim jonima u rastopima koji sadrže jednu neorgansku so i jedno organsko jedinjenje i/ili vodu pri različitom sastavu sistema i na različitim temperaturama. Jedan od sistema je amonijum-nitrat – acetamid – voda sastava NH<sub>4</sub>NO<sub>3</sub>∙(2,61-z)CH<sub>3</sub>CONH<sub>2</sub>∙zH<sub>2</sub>O (z = 0,0 1,61 i 2,61), a drugi sistem je amonijum–nitrat – dimetilsulfoksid (DMSO) sastava NH<sub>4</sub>NO<sub>3</sub>∙zDMSO (z = 1 – 6), na različitim temperaturama (35, 45, 55 i 65 <sup>o</sup>C). Cilj ovog istraživanja je bio određivanje stabilnosti kompleksa kobalta koji se grade sa sa halogenidnim jonima i komponentama rastvarača, pronalaženje kvalitativne i kvantitativne zavisnosti konstanti stabilnosti kompleksa kobalta(II) sa halogenidnim jonima od temperature i molskog odnosa komponenti sistema NH<sub>4</sub>NO<sub>3</sub>∙(2,61-z)CH<sub>3</sub>CONH<sub>2</sub>∙zH<sub>2</sub>O odnosno NH<sub>4</sub>NO<sub>3</sub>∙zDMSO, određivanje termodinamičkih parametara koji karakterišu reakcije asocijacije u ovim sistemima.</p> / <p>In this dissertation the complex formation between cobalt(II) and halide ions in the melts consisting of one inorganic salt, an organic compound and/or water has been studied at different temperatures. Two molten salt systems have been investigated: 1) ammonium nitrate-acetamide-water system NH<sub>4</sub>NO<sub>3</sub>∙(2,61-z)CH<sub>3</sub>CONH<sub>2</sub>∙zH<sub>2</sub>O (z = 0.0 1.61 2.61) and 2) ammonium nitratedimethyl sulfoxide NH<sub>4</sub>NO<sub>3</sub>∙zDMSO (z = 1 – 6), at four different temperatures: 35, 45, 55 and 65 <sup>o</sup>C. The purpose of this work was to determine stability of cobalt(II) complexes formed with the halide ions and the components of the solvents, to discribe the qualitative and quantitative relationships between the stability of the complexes and the melt composition, as well as the changes in the cobalt(II) coordination due to a complex formation. Thermodynamic parameters for cobalt(II) – halide association process in these melts were alsodetermined.</p>
