Abstract:V magistrskem delu smo raziskovali derivate amonijaka, in sicer metilamine (dimetilamine, trimetilamine in tetrametilamine) ter njihove koordinacijske spojine. Predpostavili smo, da bodo metilamini (dimetilamini, trimetilamini in tetrametilamini) tvorili trdne produkte z vodikovimi halogenidi, kjer smo izbrali halogeni element klor. Reaktante smo sintetizirali z reakcijo nevtralizacije pri sobni temperaturi ter s segrevanjem na vodni kopeli. Reakcija med metilaminom ter klorovodikovo kislino je bila uspešna, tako da smo dobljeni produkt metilamonijev klorid karakterizirali ter potrdili z rentgensko monokristalno analizo. Ostali produkti reakcij so bili neobstojni, tako da smo jih označili za neuspešne sinteze. Glede na to, da se metilamini (dimetilamini in trimetilamini) obnašajo podobno kot amonijak, smo jih uporabili pri tvorbi koordinacijskih spojin. Za centralni atom smo izbrali baker, ki smo ga dodajali v obliki bakrovih(II) spojin (CuSO4·5H2O, Cu(CH3COO)2,Cu(CH3COO)2·H2O ter CuCl2). Sinteze koordinacijskih spojin so potekale pri različnih množinskih razmerjih (1:1, 2:1 ter 4:1) in različnih topilih (metanol, etanol, destilirana voda ter acetonitril). Sinteze reaktantov smo izvedli z mešanjem pri sobni temperaturi ter z reakcijo na refluksu. Za karakterizacijo nastalih kristalov smo uporabili termogravimetrično metodo (TGA) in monokristalno rentgensko analizo. Uspešno smo sintetizirali štiri nove spojine, katerim smo določili pripadajočo strukturo ter jih opisali. Ostali analizirani vzorci so se izkazali za že znane spojine, katerih strukture so karakterizirane ter opisane v člankih.

Title:Reactions of methylamines with hydrogen halogenides and their applications in the synthesis of coordination compounds
Abstract:In this master thesis ammonia derivatives, namely methylamine (dimethylamine, trimethylamine and tetramethylamine) and their coordination compounds were investigated. We assumed that methylamines (dimethylamines, trimethylamines and tetramethylamines) will form solid products with hydrogen halide, where the selected halide element was chlorine. Neutralization reaction with elevated temperature and at room temperature was used to synthesize the reactants. Reaction between methylamine and hydrogen chloride was successful, and the obtained product methylammonium chloride was characterised and confirmed with single crystal X-ray diffraction analysis. Other products of reactions were unstable and unsuccessful. Considering that methylamines (dimethylamines and trimethylamines) behave similar to ammonia, we used them to form coordination compounds. Copper was used as the central atom and added as copper(II) compounds (CuSO4·5H2O, Cu(CH3COO)2,Cu(CH3COO)2·H2O and CuCl2). For the synthesis of coordination compounds, we used different molar ratios (1:1, 2:1 and 4:1) and solvents (distilled water, ethanol, methanol and acetonitrile). We synthesized reactants with stirring at room temperature and with reaction of reflux. Formed crystals were characterised with thermogravimetric analysis (TGA) and single crystal X-ray diffraction analysis. We successfully synthesised four new compounds, to which we determined corresponding structure. Other analysed samples were already known compounds, which we can find characterised and described in different articles.
