Abstract

A single crystal of Co8(tacn)8(CN)12 has been characterized by microelectrospray ionization mass spectrometry. The spectra obtained by use of Fourier transform ion cyclotron resonance (FT-ICR), ion trap and quadrupole mass spectrometers show the +4, +3, and +2 charge states of the cluster. With the aid of a 9.4 tesla FT-ICR mass spectrometer it was possible to resolve the isotope pattern for each individual charge state. The data collected suggest that microelectrospray renders spectra which are more specific to the intact molecule, whereas more fragmentation is induced under normal electrospray conditions. The present data suggest that microelectrospray is a powerful tool for characterization of Prussian blue complexes.
