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.
