Fig. 9. Partial electrospray mass spectrum of redissolved crystals of [Ru4Cd12(Lph)12(Lnaph)12](PF6)7(BF4)25 showing the sequence of signals associated with progressive loss of anions. For each charge, the presence of multiple closely-spaced signals is associated with different combinations of [BF4]– and [PF6]– anions. The inset shows the expansion of the set of signals around m/z 1780 for the 8+ ions: the number of [BF4]– and [PF6]– anions for each is shown in parentheses. Thus, the signal at m/z 1768 corresponds to {[Ru4Cd12(Lph)12(Lnaph)12](BF4)19(PF6)5}8+, etc. For high-resolution expansions, see ESI.† .
