20.500.12556/DKUM-97333 Sinteza in karakterizacija koordinacijskih spojin niklja z izbranimi N, S-ligandi magistrsko delo Synthesis and characterization of nickel coordination compounds with selected N,S-ligands V sklopu magistrskega dela smo sintetizirali koordinacijske spojine niklja (Ni) z izbranimi N,S-ligandi: 2-piridintioamidom, 4-piridintioamidom in 2-aminobenzotiazolom. Sinteze smo izvajaliz mešanjem raztopin Ni soli in ligandov pri sobni temperaturi ter s sintezo pod refluksom. Namen zaključnega dela je bila sinteza novih koordinacijskih spojin ter njihova karakterizacija z uporabo termogravimetrične analize (TGA) in rentgenske difrakcije na monokristalu (SCXRD). V eksperimentalnem delu smo, poleg izbranih ligandov, uporabili štiri Ni soli: Ni(II) acetat tetrahidrat, Ni(II) nitrat heksahidrat, Ni(II) 2,4-pentandionat in Ni(II) sulfat heksahidrat. Najprej smo preverili topnost reaktantov v izbranih topilih, nato pa izvedli serijo sintez z različnimi kombinacijami topil, soli in ligandov. Produkte smo najprej vizualno ocenili, izbrane vzorce pa dodatno analizirali s TGA in SCXRD. Del sintez smo ponovili tudi pod refluksom. Reakcija med 2-piridintioamidom in Ni(II) nitratom heksahidratom v mešanici deionizirane vode in acetonitrila je pri sintezi pod refluksom vodila do nastanka nove koordinacijske spojine s kationskim kompleksom, katere molekulsko strukturo smo delno določili. Uspešno smo sintetizirali in določili molekulski strukturi dveh novih koordinacijskih spojin z Ni(II) 2,4-pentandionatom v raztopini MeOH, ki sta nastali po obeh sinteznih postopkih. Nekateri produkti 2-aminobenzotiazola so bili obetavni, vendar jih ni bilo mogoče ustrezno karakterizirati. Poskusi s 4-piridintioamidom pa niso vodili v sintezo novih koordinacijskih spojin. Rezultati kažejo, da so izbrani N,S-ligandi primerni za nadaljne raziskave na področju koordinacijske kemije, pri čemer bo treba podrobneje preučiti vpliv topil in reakcijskih pogojev. As part of this thesis, we synthesized nickel (Ni) coordination compounds with selected N,S ligands: 2-pyridinethioamide, 4-piyridinethioamide and 2-aminobenzothiazole. The syntheses were carried out by mixing solutions of Ni salts and ligands at room temperature, as well as by reflux synthesis. Thea im of the thesis was synthesis of new coordination compounds an their characterisation using themogravimetric analysis (TGA) and single-crystal X-ray diffraction (SCXRD). In the experimental work, in addition to the chosen ligands, four Ni salts were used: nickel(II) acetate tetrahydrate, nickel(II) nitrate heksahidrat, nickel(II) pentane-2,4-dionate and nickel(II) sulfate hexahydrate. First, the solubility of the reactants in the selected solvents was examined, followed by a series of syntheses employung different combinations of solvents, salts and ligands. The products were initially evaluated visually, while selected samples were further analyzed by TGA and SCXRD. A portion of the syntheses was also repeated under reflux conditions. The reaction between 2-pyridinethioamide and nickel(II) nitrate hexahydrate in a mixture of deionized water and acetonitrile under reflux resulted in the formation of a new coordination compound with a cationic complex, whose molecular structure was partiallz determined. We successfully sythesized and determined the molecular structures of two new coordination compounds with nickel(II) pentane-2,4-dionate in methanol solution, obtained by both synthetic approaches. Some products involving 2-aminobenzothiazole appeared promising; however, they could not be adequately characterized. Experiments with 4-pyridinethioamide did not yield new coordination compounds. The results indicate thate the selected N,S-ligands are suitable for further research in cooordination chemistry, with additional studies needed to clarify the influence of solvents and reaction conditions.
