Abstract
(Formula presented) compounds (Formula presented) were studied for average Li concentration (Formula presented) using photoelectron spectroscopy. Strong evidence is found for the formation of (Formula presented) dimers, as well as a second phase. The study suggests that the smallest alkali-metal Li bonds to (Formula presented) largely ionically for certain configurations. An investigation of the Li (Formula presented) level shows that under certain conditions the energetics favor a backdonation of the transferred electron to the Li ion.
