Abstract

The production of aluminum cluster tetra-anions, and thus the first observation of a tetra-anionic metal cluster in the gas-phase, is reported. The aluminum cluster polyanions were generated by use of the “electron-bath technique.” The smallest tetra-anion observed was Al2154-, containing 14% fewer atoms than expected from classical estimates of the tetra-anion appearance size.
