Caught by the octopus: The first structurally characterized metallasilatranes exhibit strong, formally dative Pd→Si and Pt→Si bonds (see picture; C gray, N blue, Si red, S yellow, Cl green, Pt black). The Si atoms are hexacoordinate, and the transition‐metal (TM) atom is a lone‐pair donor. Short TMSi separations, pronounced upfield 29Si NMR signals, and strong Si–Pt coupling show the interaction between
