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. 相似文献
