Dedicated to the recognition of the many contributions to mass spectrometry of Jesse (Jack) Beauchamp on his 60th birthday.
The molecular weights of homocubane clusters, [M8L6]4- where M = CuI and AgI, containing 1,1-dicyano-ethylene-2,2-
dithiolate ligands have been determined by 252Cf-plasma desorption mass spectrometry. In addition to the expected parent
ion, an unexpected pentaanionic cluster also was observed for both metal systems. These studies affirm the versatility of
252Cf-PDMS for providing a rapid verification of the purity and formulation of high nuclearity cluster compounds. (Int J
