The study outlines our initial results that contribute to a better understanding of MAO/MgCl2 (MAO = methylaluminoxane) incorporation in the Cp2ZrCl2/MAO/MgCl2 catalytic system, which is currently of global industrial use. We show here that the[Al3(μ3-O)(Me)5]2+ moiety can be trapped by the tetrapodal [Mg3Cl4(thffo)4(THF)]2- macrounit to form a cluster [Al3Mg3(μ3-O)(thffo)4(Me)5Cl4(THF)] (thffo = 2-tetrahydrofurfuroxide). From this perspective, this macrounit might be considered as a part of the MgCl2 support surface, which fulfills the requirement of a Al3(μ3-O) core.
