Abstract:
Describes the generation and characterisation of high nuclearity carbonyl clusters from a range of tri-metallic parent precursors using UV laser desorption/ionisation mass spectrometry. By comparing and contrasting the results of known pyrolysis/thermolysis reactions with the laser desorption studies of [Os3(CO)12] and its derivatives, the aim is to achieve an understanding of the aggregation mechanisms, which enable the generation of such materials in the gas phase and therefore predict the formation, nuclearity and structure of new cluster materials. Describes the generation and characterisation of high nuclearity mixed metal carbonyl clusters from a range of parent precursors of the form [M2M'(CO)14] (where M = Re of Mn and M' = Os or Ru) using UV laser desorption/ionisation mass spectrometry. Provides a study of novel cyclic clusters generated from [HM(CO)4]n (where n = 3 and M = Mn and Re) using laser desorption ionisation mass spectrometry (LDI-MS). Similar clusters species have been synthesised in solution, from clusters of the form [HM(CO)4]n (where n = 2), promoted by anionic initiators, such as [M(CO)5]- (where M = Re) and further characterised using electrospray mass spectrometry. Electrospray ionisation mass spectrometry (ESI-MS) vs. Laser desorption ionisation mass spectrometry (LDI-MS) applied to the characterisation of anionic clusters.
