  Preparation and Characterization of Lithium Imidoalanate Complexes Li₂[(RN)₄(AlH₂)₆] (R = Me or ^tBu):  First Examples of Aluminum-Rich Imidoalanes with an Adamantoid Structure

  摘要：

  Whereas methylammonium chloride, [MeNH3]Cl, reacts with LiGaH4 in an ether solution to give, according to the conditions, either the adduct MeH2N center dot GaH3 or the cationic derivative [(MeH2N)(2)GaH2]Cl-+(-), the corresponding reaction of [MeNH3]Cl or [(BuNH3)-Bu-t]Cl with LiAlH4 proceeds mainly, with H-2 elimination, to the imidoalane Li-2[(RN)(4)(AlH2)(6)] (R = Me, 1, or Bu-t, 2). The crystal structure of 1 center dot 2Et(2)O reveals, for the first time, anionic units with an adamantane-like Al6N4 skeleton. The Li cations exist at two distinct sites, each linked via Li(mu-H)Al bridges to two [(MeN)(4)(AlH2)(6)](2-) cages. Despite disordering of the Bu-t groups, the crystal structure of 2 evidently includes analogous anionic units. By contrast, the main product of the reaction between [(PrNH3)-Pr-i]Cl and LiAlH4 under similar conditions is the known neutral, hexameric imidoalane [(PrNAlH)-Pr-i](6), 3, the crystal structure of which has been redetermined.

  The reaction of LiGaH4 with an excess of the hydrochloride of a primary amine RNH2 in ether solution yields in [(RH2N)2GaH2]Cl (R = Me, 1, or iPr, 2) additional examples of cationic gallane derivatives. The cation [(iPrH2N)2GaH2]+ reacts further with LiGaH4, also in ether solution, with H2 elimination and formation of the trigallium cationic derivative [(iPrH2N)GaH2NHiPr}2GaH2]Cl, 3.

  LiGaH 4 与醚溶液中过量的伯胺RNH 2 盐酸盐的反应产生[(RH 2 N) 2 GaH 2 ]Cl(R = Me，1或iPr，2)阳离子镓烷衍生物的另外实例。阳离子 [(iPrH2N)2GaH2]+ 与 LiGaH4 进一步反应，也在乙醚溶液中，H2 消除并形成三镓阳离子衍生物 [(iPrH2N)GaH2NHiPr}2GaH2]Cl, 3. [(iPrH2N)2GaH2 的长时间放置]Cl 在 LiCl 存在下导致 Ga-H 被 Ga-Cl 键部分交换，以低产率分离出 [(iPrH2N)2GaH2]Cl 晶体，其中约 7% 的 H 原子连接Ga 被 Cl 取代。所有化合物 1-4 都已通过晶体学表征，讨论结果涉及对 [RNH3]Cl 和 LiMH4（M = Al 或 Ga）开放的不同反应途径。
