Abstract
V svojem diplomskem delu sem se osredotočila na pripravo koordinacijskih spojin cinka(II), ki poleg pikolinata (aniona pikolinske kisline) vsebujejo etanolamin. Hkrati sem raziskovala reakcijski sistem kinaldinat/etanolamin. Kot izhodni reagent sem uporabila Zn(pic)$_2$, ki sem ga pripravila iz cinkovega(II) oksida in pikolinske kisline. Pri različnih reakcijskih pogojih sem izolirala [Zn(pic)$_2$(ea)], v tem kompleksu se etanolamin veže dvovezno kelatno preko aminskega dušika in hidroksilnega kisika. Pridobljene spojine sem analizirala z infrardečo spektroskopijo. Rezultati prispevajo k boljšemu razumevanju vpliva topila, temperature in izhodnih reagentov na sintezo koordinacijskih spojin cinka(II) z etanolaminom.

Title:Reactions of zinc(II) compounds with ethanolamine
Abstract:
In my diploma thesis, I focused on the preparation of zinc(II) coordination compounds containing both picolinate (the anion of picolinic acid) and ethanolamine. At the same time, I investigated the quinaldinate/ethanolamine reaction system. As the starting reagent, I used Zn(pic)$_2$, which I prepared from zinc(II) oxide and picolinic acid. Under various reaction conditions, I isolated [Zn(pic)$_2$(ea)]. In this complex, ethanolamine is coordinated in a bidentate chelating manner through the amine nitrogen and hydroxyl oxygen atoms to the zinc(II) ion. The obtained compounds were analysed using infrared spectroscopy. The results contribute to a better understanding of the influence of solvent, temperature, and starting reagents on the synthesis of zinc(II) coordination compounds with ethanolamine.

Keywords:coordination chemistry, ligand, zinc(II), ethanolamine, picolinate
