Reaction of the chiral lithium stannate [HC{SiMe 2 N[ (S) –CH(Me)Ph]} 3 SnLi(thf)] ( 1 ) with Me 3 SnCl gave the corresponding distannane [HC{SiMe 2 N[ (S) –CH(Me)Ph]} 3 Sn–SnMe 3 ] ( 2 ) in good yield. Its [2,2,2]bicyclooctane‐related cage structure, comprising the trisilylsilane unit and the triamido‐tin fragment, as well as the Sn–Sn bond (2.7978(15)–2.8020(15) Å in the three crystallographically independent molecules) were established by a single crystal X‐ray structure analysis: Space proup P 3, Z = 3, lattice dimensions at 293(2) K: a = 17.724(3), c = 10.597(2) Å, R = 0.0374.
