The positive‐ion fast‐atom bombardment (FAB) mass spectra of the biniclear [CNRu(L2)CNRu(L'2)CN]+ and trinuclear [CNRu(L2)CNRu(L2CNRu(L2)CN]2+ complexes (L=2,2′‐bipyridine; L' = 2,2′‐bipyridine or 1,10‐phenanthroline) have been investigated and compared with those of the mononuclear NCRu(L'2CN species. The FAB fragmentation patterns of the mononuclear species are interpreted by a combination of simple losses of neutral polypyridine ligands andHCN molecules and provide useful information for the understanding of the gas‐phase decomposition of the oligimeric species.

Abstract
The positive‐ion fast‐atom bombardment (FAB) mass spectra of the biniclear [CNRu(L2)CNRu(L'2)CN]+ and trinuclear [CNRu(L2)CNRu(L2CNRu(L2)CN]2+ complexes (L=2,2′‐bipyridine; L' = 2,2′‐bipyridine or 1,10‐phenanthroline) have been investigated and compared with those of the mononuclear NCRu(L'2CN species. The FAB fragmentation patterns of the mononuclear species are interpreted by a combination of simple losses of neutral polypyridine ligands andHCN molecules and provide useful information for the understanding of the gas‐phase decomposition of the oligimeric species.
