摘要：

A number of mixed-valence complexes containing Ru-III(NH3)(4)(X) (X=NH3, py) units cyano bridged to -Ru-II(bpy)(2) or -Os-II(bpy)(2) moieties have been examined by positive electrospray (ES) and Cs+ fast ion bombardment (FAB) mass spectrometry. Both sets of data yielded a substantial [M-PF6](+) signal and a number of characteristic fragment ions involving the multiple loss of the PF6- anion. ES data provided clear information on multiply charged ions as well as a strong indication of Ru-NH3 bond weakening when Ru-III(NH3)(5) units are cyano bridged to Os-II. The advantages of ES mass spectrometry for this class of compounds and the gas-phase redox chemistry of the investigated ions are discussed.
