20.500.12556/DKUM-82188 Sinteza in karakterizacija spojin železovega sulfata z aminopiridini magistrsko delo Synthesis and characterization of iron sulfate compounds with aminopyridines Namen magistrskega dela je bila sinteza spojin železa z aminopiridini. Uporabili smo železov(II) sulfat(VI) in različne aminopiridine (2-aminopiridin, 3-aminopiridin in 4-aminopiridin). Opravljenih je bilo 24 sintez. Sinteze smo izvedli na tri načine, in sicer z mešanjem pri sobni temperaturi, pod refluksom in solvotermalno sintezo. Kot topili sta bila v večini primerov uporabljena metanol in N,N-dimetilformamid. Sintezni produkti so bili karakterizirani z infrardečo spektroskopijo in rentgensko analizo na monokristalu. Sintetizirali smo že dve znani in objavljeni spojini, bis(2-aminopiridin) sulfat ter bis(4-aminopiridin) sulfat monohidrat. Uspelo nam je sintetizirati tudi novo spojino, katere struktura še ni objavljena, kristalohidrat 3-aminopiridinijev sulfat, 6C5H7N2+ · 3SO42- ∙ 3H2O. Snov ima veliko asimetrično enoto, ki vsebuje šest 3-aminopiridinijevih kationov, tri sulfatne ione in tri molekule vode. Veliko število vodikovih vezi vpliva na asimetrično strukturo. Spojina kristalizira v triklinskem kristalnem sistemu. The aim of this master's thesis was to synthesise iron compounds with aminopyridines. Iron(II) sulphate(VI) and different aminopyridines (2-aminopyridine, 3-aminopyridine and 4-aminopyridine) were used. 24 syntheses were carried out in three ways, by mixing at room temperature, by carrying out a synthesis under reflux and by conducting a solvothermal synthesis. In most cases, methanol and N,N-dimethylformamide were used as solvents. Synthesised products were characterised using infrared spectroscopy and the single crystal X-ray analysis. We synthesised two known and published compounds, bis(2-aminopyridine) sulphate and bis(4-aminopyridine) sulphate monohydrate. In addition, we managed to synthesize a new compound, whose structure has not yet been published, namely crystal hydrate 3-aminopyridine sulphate, 6C5H7N2+ · 3SO42- ∙ 3H2O. The substance has a large asymmetric unit, containing six 3-aminopyridine cations, three sulphate ions and three water molecules. A great number of hydrogen bonds have an effect on the asymmetric structure. The compound crystallises in the triclinic crystal system. aminopiridini koordinacijske spojine kristal ligandi železov(II) sulfat(VI) heptahidrat aminopyridines coordination groups crystal ligands iron(II) sulphate(VI) heptahydrate true true false [S.
