Abstract

V magistrskem delu so opisane reakcije izhodne cinkove spojine, [Zn(kinal)2(H2O)], z izbranimi alkoholamini. Alkoholamini imajo dve različni funkcionalni skupini: aminsko in hidroksilno. Obe funkcionalni skupini se lahko koordinirata na ione kovin prehoda. Opisane reakcije naj bi vodile do novih koordinacijskih zvrsti, ki bi poleg koordiniranega kinaldinatnega iona (kinal–) vsebovale še izbrani alkoholaminski ligand: N-metiletanolamin (Nmea), 3-amino-1-propanol (3apOH) ali dietanolamin (deaH2). V skladu s pričakovanji ob reakcijah izhodne spojine z alkoholamini, kelatno vezan kinaldinat ostaja koordiniran na cinkov(II) ion, poteče pa substitucija vode z alkoholaminskim ligandom. Reakcije sem izvedla pri različnih temperaturah, ali na sobni temperaturi ali ob segrevanju pri refluksu oziroma v avtoklavu pri 105 °C. Uporabila sem različna topila: acetonitril, metanol, absolutni etanol, 2-propanol in tudi različne kombinacije omenjenih topil. Izbira topil je bila določena s topnostjo reagentov in produktov. Izolirani trdni produkti so bili okarakterizirani z različnimi eksperimentalnimi tehnikami, ki se rutinsko uporabljajo v laboratorijih na Katedri za anorgansko kemijo. Te tehnike so infrardeča (IR) spektroskopija, elementna CHN analiza, NMR spektroskopija (spektroskopija z jedrsko magnetno resonanco) in termogravimetrična (TG) analiza. V magistrskem delu so tako opisane optimizirane sinteze treh koordinacijskih spojin: cis-[Zn(kinal)2(Nmea)], [Zn(kinal)2(NH3)] in [Zn(kinal)2(3apOH)]∙CH3CN.

Secondary title: Syntheses of zinc(II) complexes with quinaldinate and selected alcoholamines
Secondary abstract: The diploma work gives a description of the reactions of the starting zinc(II) compound, [Zn(kinal)2(H2O)], with selected alcoholamines. Alcoholamines possess two different functional groups: amine and hydroxyl. Both functionalities can coordinate to transition metal ions. The described reactions should yield new zinc(II) coordination species that would contain apart from the bidentate chelate quinaldinate ion (kinal–) also an alcoholamine ligand: N-methylethanolamine (Nmea), 3-amino-1-propanol (3apOH) or diethanolamine (deaH2). In line with the expectations, the zinc(II) ions retained during the reactions the bidentate chelate quinaldinate ligands, whereas the coordinated water underwent substitution with the alcoholamine ligands. The reactions were carried out at different temperatures: either at room temperature or under reflux or at 105 °C in the autoclave. The choice of solvents, acetonitrile, methanol, absolute ethanol, 2-propanol or their combinations, was dictated by the solubility of reagents and products. The isolated solids were characterized by the experimental techniques that are routinely used in our laboratories. These techniques are: vibrational infrared (IR) spectroscopy, elemental (CHN) analysis, NMR spectroscopy and theromogravimetric (TG) analysis. The presented work summarizes optimised syntheses of three coordination compounds: cis-[Zn(kinal)2(Nmea)], [Zn(kinal)2(NH3)] and [Zn(kinal)2(3apOH)]∙CH3CN.
