implemented quickly and easily to identify the nature of the “GaI” in hand. The “GaI” prepared from exhaustive reaction times (100 min) is shown to possess Ga2I3 and an overall formula of [Ga0]2[Ga+]2[Ga2I62–], while the “GaI” prepared with the shortest reaction time (40 min) contains GaI2 and has the overall formula [Ga0]2[Ga+][GaI4–]. Intermediate “GaI” samples were consistently shown to be fractionally
已详细研究了用不同反应时间制备的“ GaI”样品的不同结构和反应活性。通过FT拉曼光谱,粉末X射线衍射,71 Ga固态NMR光谱和127 I核四极共振(NQR)进行的分析为所制备的每个“ GaI”样品的结构提供了具体证据。这些技术可广泛使用,并且可以快速轻松地实施以识别手中的“ GaI”的性质。由详尽的反应时间(100分钟)制备的“ GaI”显示具有Ga 2 I 3和整体式为[Ga 0 ] 2 [Ga + ] 2 [Ga 2 I6 2- ],而“Gal的”用最短的反应时间(40分钟)制备包含Gal的2和具有整体式[嘎0 ] 2 [嘎+ ] [Gal的4 - ]。中间“ GaI”样品始终如一地显示是由上述两种制剂中的每一种组成,没有其他可区分的相。然后显示这些“ GaI”相在与阴离子型双(膦基)
硼酸酯配体反应后产生独特的产物。早期“ GaI”的反应产生了独特的膦Ga(II)二聚配位化合物(3
