20.500.12556/RUL-149544 Priprava in reakcije izbranih cinkovih(II) kompleksov z amoniakom Preparation and reactions of selected zinc(II) ammino complexes Po že znanih sinteznih poteh smo pripravili dve koordinacijski spojini cinka(II) z amonijakom, [Zn(NH3)4](BF4)2 in [Zn(NH3)4](PF6)2. Pri reakcijah iona [Zn(NH3)4]2+ v vodni raztopini amonijaka s kinaldinsko kislino je izkristalizirala spojina, ki je vsebovala tako koordiniran kinaldinat kot amonijak, [Zn(quin)2(NH3)]. Pri reakcijah [Zn(NH3)4]2+ v vodni raztopini amonijaka s pikolinsko kislino je izkristalizirala že znana spojina s koordiniranim pikolinatom in vodo, [Zn(pic)2(H2O)3)]∙2H2O, pri reakcijah s pirazinojsko kislino pa zmes [Zn(pyraz)2(H2O)2] in [Zn(pyraz)2(H2O)]. Izbrane komplekse z amonijakom smo reagirali pri sobnih pogojih z acetonitrilom. Le v primeru [Zn(quin)2(NH3)] je bila potrjena reakcija amonijaka z acetonitrilom. Pri tej reakciji je nastal acetamidin Following the known synthetic procedures, two zinc(II) ammine coordination compounds, [Zn(NH3)4](BF4)2 and [Zn(NH3)4](PF6)2, were prepared. Reactions of [Zn(NH3)4]2+ with quinaldinic acid in aqueous ammonia has afforded [Zn(quin)2(NH3)], a compound that contains coordinated quinaldinate and ammonia. Analogous reactions of [Zn(NH3)4]2+ with picolinic acid have afforded an already known [Zn(pic)2(H2O)3)]∙2H2O, a complex with coordinated picolinate and water. Similar reaction with pyrazinoic acid has produced a mixture of [Zn(pyraz)2(H2O)2] and [Zn(pyraz)2(H2O)]. Selected ammine complexes have been reacted with acetonitrile at ambient conditions. Only in the case of [Zn(quin)2(NH3)], a reaction of ammonia with acetonitrile has been undoubtely confirmed. The latter reaction produces acetamidine. cink amonijak koordinacijska kemija zinc ammonia coordination chemistry true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2023-09-07 11:26:47 2023-09-07 11:26:47 2023-09-14 13:34:21 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 22634 164458243 Trobevsek_Laura_-_Priprava_in_reakcije_izbranih_cinkovih(II)_kompleksov_z_amoniakom.pdf Trobevsek_Laura_-_Priprava_in_reakcije_izbranih_cinkovih(II)_kompleksov_z_amoniakom.pdf 1 674E832D4F052EC006326C74AC7A1993 bd2573196e246c1f77cb16f3bbc7380b8f746520533ade0c2791600f38a8646a a93abfa8-4d60-11ee-9934-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=174028 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
