diplomsko delo

Abstract

Izvedli smo reakcije med mangovim(II) kloridom dihidratom, manganovim(III) acetatom dihidratom in manganovim(II) sulfatom monohidratom s pirazinojsko kislino v topilih: metanol, etanol in acetonitril. Reakcije so potekale pri sobni temperaturi ali pa na oljni kopeli pri višji temperaturi. Kristalizacija je potekla na zraku ali v zaprtem sistemu za kristalizacijo pri nižjem tlaku. Z manganovim(II) kloridom, sulfatom in pirazinojsko kislino nam je uspelo sintetizirati dva kompleksa, [MnCl$_2$(pyzaH)$_2$] in [MnCl$_2$(pyzaH)$_2$]n·2nH$_2$O. Za potek reakcije med manganovim sulfatom in pirazinojsko kislino je bilo potrebno dodati koncentrirano klorovodikovo kislino. Za potrditev nastanka novih kompleksov smo uporabili analizne metode: IR spektroskopija, CHN elementna analiza, termična analiza, rentgenska praškovna analiza in rentgenska strukturna analiza.

Secondary abstract:	We carried out reactions between manganese(II) chloride dihydrate, manganese(III) acetate dihydrate and manganese(II) sulfate monohydrate with pyrazinoic acid in solvents: methanol, ethanol and acetonitrile. The reactions were carried out at room temperature or in an oil bath at a higher temperature. Crystallization was carried out in air or in a closed crystallization system at a lower pressure. With manganese(II) chloride and sulfate, we managed to synthesize two complexes [MnCl$_2$(pyzaH)$_2$] and [MnCl$_2$(pyzaH)$_2$]n·2nH$_2$O. For the reaction of manganese sulfate and pyrazinoic acid it was necessary to add concentrated hydrochloric acid. To confirm the formation of new complexes, we used analytical methods: IR spectroscopy, CHN elemental analysis, thermal analysis, X-ray powder analysis and X-ray structural analysis.
