The present interest in organometallic nitrosyl complexes stems partly from their similarity with carbonyl analogues which are widely used as catalysts in industrial processes. The search for potential new catalysts among nitrosyl complexes is perhaps not surprising when it is realised that the nitrosonium ion (NO+), the species normally regarded as being co-ordinated, is isoelectronic with carbon monoxide. Further interest may be due to the fact that NO+ is also isoelectronic with molecular nitrogen and hence nitrosyl complexes may be suitable as models for co-ordinated nitrogen in the process of nitrogen fixation. In their own right nitrosyl complexes pose problems of chemical interest concerned with their structure and the bonding associated with the metal-nitrosyl bond. As part of an investigation into the geometry of co-ordinated nitrosyl this thesis presents structural data for several nitrosyl complexes of Group VIII metals .. In addition the mode of binding of the isocyanide group has been studied as well as the associated stereochemistry of the metals ruthenium, osmium and iridium. To date, structural studies have established three different modes of co-ordination for the nitrosyl group. Probably the most common involves a linear arrangement of metal, nitrogen and oxygen, the effective coordinating species being regarded as the diamagnetic nitrosonium ion (NO+).
