Mass spectral peaks of cluster ions believed to be due to penta‐μ‐acetato‐μ 4 ‐oxo‐tetramagnesium and tri‐μ‐acetato‐μ 3 ‐oxo‐trimagnesium, or the corresponding zinc compounds, were detected when magnesium acetate or zinc acetate was heated on a tungsten filament and impacted at the same time by an electron beam. Structures of these non‐transition metal complexes are analogues of the so‐called ‘electron‐sponge’ complexes, [Ru 3 O(OAc) 6 L 3 ]. Previously reported new cluster ions from lithium acetate are formulated by similar structures.
