The chemistry of some dithiadiazolyls and their platinum complexes

Abstract

The work outlined in this thesis is mainly concerned with the preparation and reactions of dithiadiazolylium salts, dithiadiazolyls and their Pt complexes. Chapter one outlines the chemistry, the synthesis and properties of dithiadiazolylium salts and dithiadiazolyls. Chapter two is concerned with the preparation and characterisation of some dithiadiazolyls and their platinum complexes, and comprehensive DSC and Ultraviolet/visible spectroscopic studies of these complexes, highlights some of their properties. Chapter three outlines the preparation and characterisation of some fluorine substituted dithiadiazolyls and their platinum complexes. It also discusses the crystal structures of the complex Pt(_3)[PPh(_3)](_4)[3,4-F(_2).C(_6)H(_3).CNSSN](_2) and the fluorine substituted dithiadiazolyls (2,3-F(_2).C(_6)H(_3).CNSSN)(_2) and (2,5-F(_2).C(_6)H(_3).CNSSN)-Chapter four outlines the main experimental techniques which were employed throughout my research. Appendix I contains additional crystallographic data, for the crystal structures mentioned previously, while Appendix II lists all the colloquia, lectures and seminars attended by the author.
