Unique amongst metalloid clusters is one described in the Communication from H. Schnöckel et al. on page 8201 ff. A Si centered Al 44 structural unit is protected by 12 AlR units to give Si§Al 56 R′ 12 . The Si atom itself has a coordination number of 4 and the Al atoms in the SiAl 44 scaffolding form four Al‐centered cuboctahedra. The formation of this structure by doping with one Si atom is a reminder that care should be taken in the interpretation of the characterization data of such nanoscale metal particles.
