Cluster ion formation by fast atom bombardment mass spectrometry of 15 binary mixtures of tetraalkylammonium halide salts in liquid matrices has been studied. In some instances the replacement of even one of the cations in the pure cluster ion by a different cation to yield mixed cation cluster ions has a destabilizing effect on the clusters, and results in the disappearance of the ion intensity anomalies. The effect of the anion and cation sizes and also the matrix composition on the stability of mixed cluster ions is discussed.
