Structures of the potassium aluminate [{K2(Me3AlOBut)2·pmdeta}∞] and [{K(pmdeta)2}+(AlMe4)–]: how the nature of the alane reagent determines which of these products form from alkoxide-containing reaction mixtures

Abstract

Equimolar mixtures of AlMe₃, Bu^tOK and pmdeta produce either title compound depending on whether solvent-free, dimeric [(AlMe₃)₂] or the amine-solvated monomer [Me₃Al·(H)N(CH₂Ph)₂] is used as the source of the alane.
