Thesis (MSc (Chemistry and Polymer Science))--Stellenbosch University, 2008. / In this study the coordination of ligands with several coordination sites, 2-aminoazoles (2-
amino-4-methylthiazole), 2-aminobenzothiazole, 2-aminobenzoimidazole and 2-
aminothiazoline and a biguanidine (N-(2-methylphenyl)imidodicarbonimidic diamide) to
soft metal centres [gold(I) (group 11), chromium(0) (group 6) and tungsten (0) (group 6)]
was investigated. The aminoazoles have three coordination sites, an exocyclic amine
nitrogen, an endocyclic imine nitrogen and an endocyclic thioether sulphur. The
biguanidine ligand has three sites for deprotonation, one central amine and two imine
nitrogens, and at least five sites available for nitrogen coordination.
