Synthesis and Molecular Structure of a Hexaaminodistannane Comprising two Identical Triaminotin Subunits

Reaction of the previously characterized lithium stannate HC{SiMe₂N(4‐CH₃C₆H₄)}₃SnLi(thf)₃] ( 1 ) with AgCl afforded the corresponding distannane HC{SiMe₂N(4‐CH₃C₆H₄)}₃Sn]₂ ( 2 ) as the product of an oxidative coupling in good yield. Its 2, 2, 2]bicyclooctane‐related cage structure, comprising the trisilylmethane unit and the triamido‐tin fragment, as well as the Sn‐Sn bond (2.8204(4)Å) were established by single crystal structure analysis: Space group group P2₁/n, Z = 2, lattice dimensions at 120(2) K: a = 13.6515(3), b = 15.8391(3), c = 16.3522(3)Å, β = 102.7760(10)°, R₁ = 0.0347.
