Reaction of AlMe3 or [AlMe3·py] with the pendant arm OH-funtionalised 1,4,7-triazacyclononane proligands, HL1 or HL2, affords the four- and five-coordinate derivatives [Al(L1)Me2] 1 or [Al2(L2)2Me4] 2 in which the pendant alkoxide O-donor and only one macrocycle N-donor is bound to Al; methyl anion abstraction from 1 yields cationic, pentacoordinate [Al(L1)Me]+ in which L1 has a tetradentate coordination
