| dc.description.abstract | The bithiazole ring system consists of two thiazole (C3NS) aromatic rings. There are many regioisomers but two of potential interest for coordination chemistry are the 2,2’-bis(1,3-thiazole) and the 4,4’-bis(1,3-thiazole), because in the syn orientation they have a bipyridyl-like core that could lead to chelating behaviour. Very few single-crystal structures are known to contain bithiazole ligands and those that are known, are mostly of the 4,4’-isomer. This thesis presents work on new ligands using the bithiazole core, reporting the synthesis and coordination chemistry of 2,2’-dichloro-4,4’-bithiazole, 5,5’-dibromo-2,2’-dimethyl-4,4’-bithiazole, and 5,5’-dibromo-2,2’-diamino-4,4’ bithiazole. In solution, the bithiazole ligands are weaker ligands than bipyridyl ligands, but when used in large-scale, and high concentration reactions, a coordination complex can be isolated. UV-vis and combustion analysis evidence are reported to support the formation of the coordination complex. In the case of coordination compounds between silver(I) and a 5,5’-dicyano-2,2’-bithiazoles core, thermogravimetric analysis, differential scanning calorimetry, and X-ray powder diffraction are used to characterize the thermal stability of the known single-crystal structures. | en_US |
