The fast atom bombardment (FAB) and field desorption (FD) mass spectrometric analysis of 18 involatile, cationic organometallic derivatives of 2,2'-bipyridine (bpy) complexes of Ru(II) and Os(II) containing eta/sup 2/-alkene, eta/sup 2/-alkyne, carbonyl, alkyl, and hydrido ligands is presented. Field desorption (FD) and fast atom bombardment (FAB) mass spectrometry are used in concert. In the area of (polypyridyl)metal complex chemistry, these techniques are powerful structural tools; the former gives information on the intact cation, and the latter, fragmentations characteristic of the ligands. The fragmentations can be interpreted on a chemical basis by invoking four concepts: redox fragmentation of metal-ligand bonds, i.e., homolytic dissociation; the simple loss of neutral ligands, depending upon their thermal liability; intramolecular, oxidative addition of coordinated bpy; reductive elimination of HX (X = Cl, H, alkyl). 20 references, 1 figure, 4 tables.
