  Synthesis of a Novel Binuclear Chlorotin(II) Alkyl and a Lithium Trialkylstannate Zwitterionic Cage Molecule:  Crystal Structures of [Sn(Cl)R^N]₂ and [(SnR^N₃)Li(μ³-Cl)Li(tmeda)]₂ [R^N = CH(SiBu^tMe₂)C₅H₄N-2]

  摘要：

  The reaction of SnCl(2) with [LiR(N)(tmeda)](2) [R(N) = CH(SiBu(t)Me(2))C(5)H(4)N-2; tmeda = N,N,N',N'-tetramethylethylenediamine)] in various stoichiometric ratios afforded a binuclear chlorotin(II) alkyl [Sn(Cl)R(N)](2) (1) and zwitterionic lithium trialkylstannate complexes [{(SnR(3)(N))Li}{(mu(3)-Cl)(Li(tmeda)(2)}(mu-Cl)] (2) and [{(SnR(3)(N))Li}(mu(3)-Cl)Li-(tmeda)](2) (3). X-ray structure analysis has shosrm that the anionic N-functionalized allryl ligand (RN)- i, 1 acts as a bridging ligand joining the two tin atoms to form an eight-membered ring in a "boat" conformation. Compounds 2 and 3 consist of one and two lithium trialkylstannate ion pairs [SnR(3)(N)](-)Li(+) bound to the chlorine atom of the [LiCl(tmeda)](2) fragment, respectively. The lithium ion in the ion pair is coordinated via the pyridyl nitrogens to form a cage.
