The fast atom bombardment (FAB) mass spectrometric behavior of some involatile polynuclear rhenium(I)-ruthenium(II) complexes of general formula [Re(CO)[sub 3](phen)(CN)-[Ru(bpy)[sub 2](CN)]n-Ru(bpy)[sub 2](CN)][sup (n+1)+] (n = 0-2, bpy = 2,2[prime]-bipyridine, phen = 1,10-phenanthroline) is presented. Singly, double, and, for n = 2, also triply charged ions were detected, and the fragmentation patterns of these ionic species were determined by studying unimolecular dissociation reactions. The decomposition pathways involve losses of CO and bpy neutral ligands, oxidative addition of coordinated bpy with expulsion of HX (X = CN[sup [minus]], PF[sub 6][sup [minus]]), and cleavage of the CN-Ru bond. 25 refs., 6 figs., 2 tabs.
