Many of these compounds may also be of import to the hydrodesulphurization process. Chapter 1 contains a brief introduction to the chemistry of sulphur which is pertinent to the remainder of this work. Chapters 2 and 3 are concerned with the reaction of the complex {M02&gS2) with various nitrogen-, oxygen- and sulphur-containing ligands, and the characterization of these products by spectroscopic and analytical methods. Chapter 4 details the reaction of some of these products with H+ and compares them to known Mo-H and Mo-S-H species. Chapter 5 explains the unexpected formation of the lattice adduct [WSC14].S8 from W(CO)6 and S2Cl2, and compares its crystal structure and reactions with the known compound [WSCl4J. Chapters 6 and 7 describe the preparation, characterization and reactions of the complexes [MoH(SAr)3(PMe2Ph)2l and [MoH(SAr)3(PMePh2) ] (SAr - tipt or tmt). The crystal structures of the complexes [MoH(tipt)3 (PMe2Ph)2 ] and [Mo(tipt)2(00)2(PMe2Ph)2] are described, and many of the reactions of these compounds are compared with those of the analogous tungsten compounds lWH(SAr)3(PMe2Ph)2] (SAr - tipt or tmt). In Chapter 8 a general discussion and summary of the preceding Chapters is given, together with some suggestions for further work.iii.
