( Cobalt ) n benzene m − cluster anions, (n,m) were generated by laser vaporization and studied both mass spectrometry anion photoelectron spectroscopy. Our assignment of the spectrum (1,2) suggests that it possesses a sandwich structure with cobalt atom located between two parallel rings, ground state this is singlet, its corresponding neutral doublet. The spectra cobalt-rich anions form (n,1) are interpreted as metal which have been solvent-stabilized their interaction with, in each case, single molecule. benzene-rich (2,3), (2,2), (3,3), tentatively suggesting extended structures for these complexes.
