Thesis (MSc (Chemistry and Polymer Science))--University of Stellenbosch, 2007.<br>A comprehensive, comparative structural study of gold(I), gold(II) and gold(III) compounds with the general formula [Aux(C6F5)y(tht)z] (tht = tetrahydrothiophene) was performed. The series of compounds included the unprecedented dinucleur gold(II) compound, tetrakis(pentafluorophenyl)bis(tetrahydrothiophene)digold(II), which could be prepared in a rational manner. This very unique compound represents the first example of an unbridged dinucleur gold(II) compound in which the gold(II) centres are not stabilis

Thesis (PhD (Chemistry and Polymer Science))—University of Stellenbosch, 2006.<br>This study describes the exploitation of numerous donor ligand possibilities presented by selected nitrogen-rich heterocyclic ligands towards gold(I). The preparation and structural characterisation of novel gold(I) complexes, apart from conventional gold(I) bonding possibilities, also encompassed a study of bi- and polytopic bonding modes within a range of multifunctional ligands.

Abstract:

A range of novel ligand systems have been developed in three distinct phases and preliminary studies have been initiated to evaluate their complexation potential. Phase I incorporated the synthesis of single strand ligand systems, which were mainly based on amino acid residues. Techniques have been developed for the attachment of these ligand systems onto, firstly, a styrene monomer, and then later onto a pseudo-styrene linking group, viz. the p-toluoyl group. The linking reactions were based on the formation of amides or esters by the reaction of an acid chloride system with an amine or alcoh

This thesis describes the preparation and characterisation of a number of homochiral coordination and metallosupramolecular assemblies.

The combination of traditional coordination chemistry and supramolecular interactions led to a range of polymeric and network structures being formed. The ligands used in this thesis can be divided into two broad categories: alkaloids and ligands derived from them, and amino acid-based ligands. In the first category three new ligands were synthesi

Some of the complexes have been structurally determined by X-ray crystallography. These complexes were found to exhibit intense emission in dichloromethane solution at 298 K, originating from metal-perturbed triplet intraligand (IL) excited states of the R-C^N^C ligand, with substantial charge transfer character from the aryl moiety to the pyridyl ring.
