Unique among metalloid clusters is the [Al 7 R 6 ] structural element presented by H. Schnöckel and co‐workers, which on the basis of the topology of its seven aluminum atoms is analogous to the metal and thus a molecular model for a single‐atom contact. The Communication on page 3579 ff. reports that the oxidation and reduction of the neutral [Al 7 R 6 ] cluster—like the removal and addition of an electron in conductance experiments—leads to drastic changes in the bond lengths within the {Al} 7 framework and thus to different bonding properties.
