Abstract

This thesis describes an investigation into the synthesis, structure, spectroscopic and electrochemical properties of a series of new gold complexes bearing N-heterocyclic carbene (NHC) and imidazole-2-thione (IMT) ligands. There were four main areas of focus: (a) oxidative halogenation of dinuclear Au1-NHC complexes derived from azolium cyclophanes, to give Au11 complexes or mixed valence Au1/Au111 complexes; (b) stable Au111 complexes bearing four N-heterocyclic carbene groups, synthesized
directly from KAuCl4 and azolium salts; (c) new cis-Au111-NHC cyanide complexes, formed by reaction of dinuclear Au111-NHC bromide complexes with NaCN; and (d) synthesis of new cyclophane imidazole-2-thione ligands and their complexes with Au1•
