20.500.12556/RUL-119546 Karakterizacija vzorcev nastalih pri reakciji (NH4)2[MoCl5(H2O)] in KOCN v piridinu Characterization of samples formed by the reaction of (NH4)2[MoCl5(H2O)] and KOCN in pyridine S pomočjo rezultatov analize prevodnosti, CHN analize, IR spektroskopije, termogravimetrične analize in UV-Vis spektroskopije sem ugotovil sestavo štirih neznanih vzorcev – obeh oborin ter monokristalov. Sinteza se je izvajala med diamonijevim akvapentakloromolibdenatom(III) in kalijevim cianatom v piridinu. Izločeno oborino smo ločili na dva različna produkta tako, da smo surovi produkt raztopili v vodi pri 60°C. V vodi ne topno komponento smo prvo odfiltrirali, drugo komponento smo iz vode oborili z dodatkom piridinijevega klorida ter ponovno odfiltrirali. Ta dva produkta smo prekristalizirali v piridinu. Vsem štirim spojinam smo analizirali prevodnost, naredili termogravimetrično analizo, rentgensko strukturno analizo, elementno CHN analizo ter UV-Vis elektronsko spektroskopijo. Dobljene spojine so [Mo(NCO)3py3], (pyH)[Mo(NCO)4py2], mer-[Mo(NCO)3py3]·2py in trans-(py2H)[Mo(NCO)4py2] Using the results of conductivity analysis, CHN elemental analysis, IR spectroscopy, thermogravimetric analysis and UV-Vis spectroscopy, I determined the composition of four unknown samples - both precipitates and single-crystals. The synthesis was performed between diammonium aquapentachloromolybdenate(III) and potassium cyanate in pyridine. The precipitate was separated into two different products by dissolving the crude product in water at 60°C. The water-insoluble component was first filtered off, the second component was precipitated from water by the addition of pyridinium chloride and filtered again. These two products were recrystallized from pyridine. The analysis which was performed for all four compounds was Conductivity analysis, thermogravimetric analysis, X-ray structural analysis, elemental CHN analysis, and UV-Vis electron spectroscopy. The compounds obtained are [Mo(NCO)3py3], (pyH)[Mo(NCO)4py2] mer-[Mo(NCO)3py3]·2py and trans-(py2H)[Mo(NCO)4py2] molibden piridin kalije cianat koordinacijska spojina ligand molybdenum pyridine potassium cyanate coordination compound ligand true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2020-09-09 17:25:01 2020-09-09 17:25:05 2022-08-31 03:53:37 0000-00-00 00:00:00 2020 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 10321 29593347 Hotko_Miha_-_Karakterizacija_vzorcev_nastalih_pri_reakciji_(NH4)2[MoCl5(H2O)]_in_KOCN_v_piridinu.pdf Hotko_Miha_-_Karakterizacija_vzorcev_nastalih_pri_reakciji_(NH4)2[MoCl5(H2O)]_in_KOCN_v_piridinu.pdf 1 C96EB29B6047D8B0BC03440C857EB076 55ca7bb750d929906ad12c6db86da196e6f2506552d66f25fa1fd551fc1cd9c5 dbe67a0a-a1b9-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=134271 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
