20.500.12556/RUL-184594 Koordinacijska kemija analogov kinaldinske kisline Coordination chemistry of analogues of quinaldic acid Koordinacijska kemija preučuje nastanek, zgradbo in lastnosti koordinacijskih spojin, v katerih se kovinski center povezuje z ligandi preko koordinacijskih vezi. V diplomskem delu smo raziskovali koordinacijsko kemijo analogov kinaldinske kisline s cinkovimi(II) ioni. Kot liganda smo uporabili deprotonirano kinolin-2,4-dikarboksilno kislino in kinurensko kislino, ki zaradi prisotnosti več donorskih atomov omogočata različne načine koordinacije na kovinski center. Eksperimentalni del je zajemal sintezo koordinacijskih spojin pri različnih reakcijskih pogojih, pri sobni temperaturi, pri pogojih refluksa in pri solvotermalnih pogojih v avtoklavu. Pri reakcijah s kinolin-2,4-dikarboksilno kislino je pri vseh pogojih nastal enak produkt [Zn(2,4-dquin)2(CH3OH)2], kjer 2,4-dquin– predstavlja deprotonirano obliko kisline. Pri reakciji v avtoklavu smo pridobili monokristale, ki so bili primerni za rentgensko strukturno analizo. Pri reakcijah s kinurensko kislino so nastali različni produkti, med njimi koordinacijski polimer [Zn(kyn)2]n·n(CH3OH) (kyn– predstavlja deprotonirano obliko kisline) in neidentificirana spojina A. Pripravljene spojine smo analizirali z infrardečo spektroskopijo, elementno CHN analizo in rentgensko strukturno analizo na monokristalu. Rezultati so omogočili vpogled v koordinacijo ligandov, sestavo spojin in njihove strukturne značilnosti. Coordination chemistry studies the formation, structure and properties of coordination compounds in which a metal center is bonded to ligands through coordination bonds. In this diploma thesis, the coordination chemistry of analogues of quinaldic acid with zinc(II) ions was investigated. Deprotonated quinoline-2,4-dicarboxylic acid and kynurenic acid were used as ligands, since the presence of multiple donor atoms enables different coordination modes toward the metal center. The experimental part included the synthesis of coordination compounds under different reaction conditions, namely at room temperature, under reflux conditions and under solvothermal conditions in an autoclave. In reactions with quinoline-2,4-dicarboxylic acid, the same product, [Zn(2,4-dquin)2(CH3OH)2], was obtained under all conditions, where 2,4-dquin– represents the deprotonated form of the acid. During the reaction in an autoclave, single crystals suitable for single-crystal X-ray diffraction analysis were obtained. In reactions with kynurenic acid, different products were formed, including the coordination polymer [Zn(kyn)2]n·n(CH3OH) (kyn– represents the deprotonated form of the acid) and an unidentified compound A. The prepared compounds were characterized by infrared spectroscopy, CHN elemental analysis and single-crystal X-ray diffraction analysis. The results provided insight into ligand coordination, compound composition and their structural characteristics. koordinacijska kemija cink kinurenska kislina kinolin-2 4-dikarboksilna kislina coordination chemistry zinc kynurenic acid quinoline-2 4-dicarboxylic acid true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-07-10 10:35:01 2026-07-10 10:35:08 2026-07-11 04:14:00 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 25939 Sedlar_Urska_-_Koordinacijska_kemija_analogov_kinaldinske_kisline.pdf Sedlar_Urska_-_Koordinacijska_kemija_analogov_kinaldinske_kisline.pdf 1 0C803CEE7A8659C7390587D3F3B681FB 6b823b38fdcb376a32d7020a1ac02d35deabfd7e8d599348e0476ea3024eab96 20810791-7c3a-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=237501 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
