The mass spectra of HC,(CO,Me), [H(cpp)] and several of its metal derivatives have been studied. In the EI mass spectra of alkali metal salts, aggregate ions [mJcpp)]+ were observed. The abundance of these and higher oligomers is increased in FAB mass spectra, ions containing up to seven (negative i
