Spontaneous metathesis of bis-chelated PdII(L-S,O)2 complexes in solution : a rp-HPLC study
(Stellenbosch : Stellenbosch University, 2008-03)
N,N-dialkyl-N-acyl(aroyl)thiourea ligands form stable chelated complexes in a cis
configuration with the platinum group metals. Such chelated complexes are generally
considered substitutionally “inert” in solution, ...
Use of the N,N-dialkyl-N’-benzoyl(thio)selenoureas as single source precursors for the synthesis of semiconducting quantum dots
(Stellenbosch : Stellenbosch University, 2008-12)
The successful preparation and structural characterization of a number of N,N-dialkyl-N’-benzoyl(thio)selenourea
ligands is described; where the intermolecular interactions are characterized by the presence of Resonance ...

Study of the pathway of heavy metals in a sewerage system
(Stellenbosch : University of Stellenbosch, 2007-03)
This thesis reports on an exploratory investigation of proposed sludge guideline limits of heavy metal (cadmium, chromium, copper, nickel, lead and zinc) concentrations for South Africa. The purpose of the study is to ...
Investigating intermolecular interactions motifs in ammonium carboxylate salts
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT:
This thesis reports an in-depth investigation of the intermolecular interaction motifs in
secondary, primary and ammonium carboxylate salts. The investigation was
conducted using the Cambridge Structural ...
Novel ion-exchange materials derived from poly(styrene-co-maleimide) and a study of the extraction and recovery of gold (III) chloride from acidic solutions
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: In this study an economical, environmentally friendly, selective and efficient process for the extraction and recovery of [AuCl4]- from aqueous acidic chloride-rich solutions, particularly those aqueous ...
High resolution NMR studies concerning the solvation/hydration and coordination chemistry of Pt (II/IV) compounds
(Stellenbosch : Stellenbosch University, 2005-12)
ENGLISH ABSTRACT: Pt(JV) complexes with S, 0-donating aroylthioureas have been synthesized by oxidative addition of
elemental halogens to the Pt(JJ) precursors, leading to the first-reported crystal structures of Pt(JV) ...
Self-association of [PtII(1,10-Phenanthroline)(N-pyrrolidyl-N-(2,2-dimethyl-propanoyl)thiourea)]+ and non-covalent outer-sphere complex formation with fluoranthene through cation-π interactions : a high resolution 1H and DOSY NMR study
