STRUCTURES OF THE POTASSIUM ALUMINATES K-2(ME(3)ALOBU(T))(2)CENTER-DOT-PMDETA)(INFINITY)] AND [(K(PMDETA)(2))(-)] - HOW THE NATURE OF THE ALANE REAGENT DETERMINES WHICH OF THESE PRODUCTS FORM FROM ALKOXIDE-CONTAINING REACTION MIXTURES()(ALME(4))()

Equimolar mixtures of AlMe(3), Bu(t)OK, and pmdeta produce either titl e compound depending on whether solvent-free, dimeric [(AlMe(3))(2)] o r the amine-solvated monomer [Me(3)Al .(H)N(CH(2)Ph)(2)] is used as th e source of the alane.
