Starting from the left and right, the initial precursors py-AlMe3/py-AlCl3 (denoted as states Me3 and Cl3) can undergo three condensation steps towards the center of the diagrams. The energy scale is referenced with respect to the final state with the tetracoordinate (4C) aluminosilicate product py-Al(OSiH3)3, which is common to both precursors (states denoted as O). In parallel, states containing the pentacoordinate analogs (with additional THF at Al) are visualized in lighter colors (5C).
