Structural Studies of Some Sulphur Bonding Ligands

<p>This thesis is a study of the structures and energetics of the metal complexes of dithizone, C6H5.N:N.C(S).NH.NH.C6H5, and thiocarbohydrazide, H2N.HN.C(S).NH.NH2. Dithizone was first prepared and studied by E. Fisher as part of his classic work on phenylhydrazine. It is a weak acid capable of forming intensely coloured metal complexes with at least twenty three elements and, since the work of Walter and H. Fischer, has been used extensively for trace metal analysis, particularly in solvent extraction procedures. The applications of dithizone in analytical chemistry have been covered in numerous review articles and have also been the subject of a book.</p>
