Larger metal aggregates do not form when the alkali‐metal ions in zeolites are reduced to low‐valent ion clusters by solvated electrons. Besides the ion cluster Na n (n‐1)+(n = 4–6) and K n (n‐1)+(n = 3,4) previously reported, the new cluster Na 3 2+was obtained selectively and reproducibly. The solvated electron were prepared in situ from highly purified Li granules and propyl‐ or butylamine. One intriguing feature of these ion clusters is the unusual nature of the valence electrons‐not bound to one atom but also not completely delocalized as in a metal.
