The seemingly simple process of the formation or dissolution of a metal is highly dynamic and mostly unknown on the atomic scale. In their Communication on page 3216 ff., A. Schnepf et al. show that the oxidation of [Ge 9 (Hyp) 3 ] − (Hyp=Si(SiMe 3 ) 3 ) with an iron(II) salt leads to Ge 18 (Hyp) 6 , the largest metalloid Group 14 cluster that has been structurally characterized to date. This cluster can be regarded as a first trapped intermediate of the formation of Ge( cF 136) from Ge 9 units.
