Since their discovery, electric and magnetic properties of thiazyls have caught significant attention and these odd-electron species have been used as building blocks in the development of molecular magnets and conductors. Furthermore, certain thiazyls present bistability and can be seen as prospective materials for molecular switches because a single radical unit can have two different magnetic states depending on the solid state packing. The latest developments in this research field have focused on thiazyl radicals capable of coordinating to transition metals and the complexes thus formed. The formation of metal complexes is expected to lead to enhanced magnetic properties as the unpaired electron on the radical unit can interact with those on the paramagnetic metal center.\r\nThis master\u00b4s thesis contains two parts. Part one is a literature review that summarizes the most recent developments in the field of radicals containing nitrogen and sulfur. The emphasis of the discussion is on the synthesis and properties of dithiadiazolyl and dithiazolyl radicals. In addition, coordination chemistry of thiazyl radicals is described. The second part of the thesis summarizes the results from experimental studies conducted during the thesis work. The main objective of the experimental work was to synthesize new thiazyl radicals and to study their coordination chemistry. Two completely new radicals were synthesized and comprehensively characterized. The first new radical is a member of a large family of 1,2,3,5-dithiadiazolyls with features similar to other members of the same class. The second new radical is a modified version of the parent dithiazolothiadiazinyl1 framework with a hydrogen atom replaced by fluorine, thereby inducing changes in the solid-state packing of the radical. The coordination of dithiazolothiadiazinyl radical to various metal centres was also examined but no coordination complexes could be isolated.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Anni Taponen (anirtapo) on 2017-05-17 21:18:51.707803.
