Abstract

Synthesised from its homonuclear components in the presence of the Lewis base TMEDA, the title heteronuclear alkoxide crystallises in an unsolvated TMEDA-free form; its novel breastplate-like Li4K4O8 cage structure, which undergoes an exchange process in arene solution as determined by dynamic NMR spectroscopic studies, displays a planar K-4 arrangement in marked contrast to the tetrahedral K-4 arrangement found in homonuclear [((BuOK)-O-t)(4)].
