  单氯gal烷，[H2GaCl] n以及与胺和膦碱加成物的分解：形成阳离子加仑衍生物。

  摘要：

  一氯镓烷[H2GaCl] n在环境温度下的热分解导致亚价镓物种的形成。现在向先前报道的Ga [HGaCl3]中添加了第二种混合价态固体Ga4 [HGaCl3] 2 [Ga2Cl6]（1），其晶体结构在150 K下显示出许多不同寻常的特征。最容易从碱和LiGaH4的盐酸盐中适当比例制备的一氯代gallane加合物不仅包括1：1分子配合物Me3P.GaH2Cl（2），还包括被证明是阳离子加仑衍生物的2：1胺配合物， [H 2 Ga（NH 2 R）2] + Cl-，其中R ＝ tBu（3a）或sBu（3b）。所有这三种配合物均已在150 K上进行了结晶学表征。

  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.
