Abstract:V magistrskem delu smo raziskovali sintezne poti, strukturne značilnosti in termične lastnosti koordinacijskih spojin prehodnih kovin kobalta in niklja s fluoropiridinskimi ligandi. Kot vir kovinskih centralnih ionov smo uporabili izbrane kobaltove in nikljeve soli, kot vir N-donorskih ligandov pa različne derivate fluoropiridina. Z usmerjenim spreminjanjem reakcijskih pogojev nam je uspelo sintetizirati več novih ter že znanih koordinacijskih spojin. Sinteze smo izvajali z reakcijami med ustreznimi kobaltovimi in nikljevimi solmi, izbranimi fluoropiridinskimi ligandi in različnimi topili, kot so voda, metanol, etanol in acetonitril pri sobni temperaturi. Monokristale, primerne za strukturno analizo, smo izolirali z nadzorovanim počasnim izparevanjem raztopin. Za natančno karakterizacijo pripravljenih spojin smo uporabili komplementarni nabor analiznih metod. Kristalno strukturo in parametre osnovne celice v trdnem stanju smo nedvoumno določili z rentgensko monokristalno analizo (XRD). Prisotnost in način vezave funkcionalnih skupin ter ligandov smo potrdili z infrardečo spektroskopijo s Fourierjevo transformacijo (FT-IR). Termično stabilnost in potek razgradnje sintetiziranih kompleksov pa smo ovrednotili s termogravimetrično analizo (TGA). Rezultati omogočajo poglobljeno razumevanje koordinacijskih spojin kobalta in niklja s fluoropiridinskimi ligandi in potrjujejo uspešno koordinacijo fluoropiridinskih ligandov na kobaltova in nikljeva centralna mesta ter razkrivajo zanimive strukturne motive in termično stabilnost sintetiziranih spojin.
Keywords:Koordinacijske spojine, kobalt(II), nikelj(II), fluoropiridini, termogravimetrična analiza.

Title:Synthesis and characterization of cobalt and nickel coordination compounds with fluoropyridine ligands
Abstract:In this master's thesis, we investigated the synthetic routes, structural characteristics, and thermal properties of new coordination compounds of the transition metals cobalt and nickel with fluoropyridine ligands. Selected cobalt and nickel salts were used as the source of central metal ions, while various fluoropyridine derivatives served as N-donor ligands. By systematically varying the reaction conditions, we successfully synthesized several new as well as previously known coordination compounds. The syntheses were carried out by reacting the appropriate cobalt and nickel salts with selected fluoropyridine ligands at room temperature. Single crystals suitable for structural analysis were isolated by controlled slow evaporation of the solutions. A complementary set of analytical methods was used for the precise characterization of the prepared compounds. The crystal structure and cell parameters in the solid state were unambiguously determined by single-crystal X-ray diffraction (XRD). The presence and coordination modes of the functional groups and ligands were confirmed by Fourier-transform infrared spectroscopy (FT-IR). The thermal stability and decomposition pathways of the synthesized complexes were evaluated by thermogravimetric analysis (TGA). The results provide a deeper understanding of cobalt and nickel coordination compounds with fluoropyridine ligands, confirm the successful coordination of the fluoropyridine ligands to the cobalt and nickel central sites, and reveal interesting structural motifs and thermal stability of the synthesized compounds.
Keywords:Coordination compounds, cobalt(II), nickel(II), fluoropyridines, thermogravimetric analysis.
