20.500.12556/RUL-186920 Sinteza in karakterizacija bakrovih spojin s 4-aminobenzoatom Synthesis and Characterization of Copper Compounds with 4-Aminobenzoate Sintetizirala sem štiri bakrove(II) spojine z anionom 4-aminobenzojske kisline (L–) iz vodne raztopine. Te so CuL2 1, Cu(L)2(nia)2 2, Cu(L)2(3OHpy)2 3 in Cu(L)2(2apy)2 4; nia - nikotinamid, 3OHpy - 3-hidroksipiridin, 2apy - 2-aminopiridin. V bazi podatkov kristalnih struktur (CSD) nisem našla takšnih ali podobnih spojin. Ponovljivost sintez, praškovnih difraktogramov in IR spektrov kaže na čistost izoliranih spojin. Z izmerjenimi masnimi deleži CHN analize sem določila njihove predvidene formule glede na teoretične vrednosti teh deležev. IR spektri se skladajo s prisotnostjo vezi v uporabljenih piridinskih ligandih in v osnovnem anionu L–. Elektronski spektri spojin 1-4 so si podobni. To se sklada s podobno komplementarno barvo in predvideno podobno koordinacijsko sfero v strukturah izoliranih spojin. Four copper(II) compounds with the 4-aminobenzoic acid anion (L–) were synthesized from aqueous solutions. These are CuL2 1, Cu(L)2(nia)2 2, Cu(L)2(3OHpy)2 3 and Cu(L)2(2apy)2 4; nia - nicotinamide, 3OHpy - 3-hydroxypyridine and 2apy - 2-aminopyridine. No such or similar compounds were found in the Cambridge Structural Database (CSD). The reproducibility of the syntheses, powder diffractograms, and IR spectra shows purity of the isolated compounds. With the measured mass fractions of the CHN analysis, their expected formulas based on the theoretical values were determined. The IR spectra are in accordance with a presence of the applied pyridine ligands as well as the principal anion L characteristic bonds. The electronic spectra of 1-4 do not differ significantly. This is in agreement with similar complementary color and the proposed similar coordination sphere of the isolated compounds' structures. koordinacijske spojine baker(II) 4-aminobenzojska kislina elementna analiza spektroskopija coordination compounds copper(II) 4-aminobenzoic acid elemental analysis spectroscopy true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-07 10:40:03 2026-09-07 10:40:08 2026-09-08 04:19:35 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 26028 Kozuh_Dea_-_Sinteza_in_karakterizacija_bakrovih_spojin_s_4-aminobenzoatom.pdf Kozuh_Dea_-_Sinteza_in_karakterizacija_bakrovih_spojin_s_4-aminobenzoatom.pdf 1 32525893BF93C2FB9FD23A3B1839F217 9b043fe66952568543d45164f10c1043e406363e94b0ef98839bfc95719b531e b7f68443-aa97-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246308 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
