The stabilities (ΔΔG-qh-tr/n) relative to our sheet model for 16,6 are also provided in Table -3 (Supporting Information), which presents the most stable anions for each oligomerization degree. Table presents a focused subset of these results, including only those species with negative formation energies or those observed experimentally. The data is organized by ionization mechanism, with entries 1-8 corresponding to Me2Al + cleavage and the remaining entries to Me -abstraction. Anions predicted by calculations but not detected in ESI-MS experiments are highlighted in light blue.
