酸性三卤化镓溶液GaX 3（X = Cl或Br）的电喷雾质谱数据揭示了单阳离子[GaX 2]（+）、[GaX（OH）]（+）和[Ga（OH）（2）]（+）通常与来自溶剂相的H2O或MeCN分子缔合。GaI 3溶液主要产生溶剂化的[Ga（OH）（2）]（+）离子。InX 3的溶液产生与溶剂分子结合的[InX 2]（+）阳离子;主要的水解阳离子是溶剂化的[InO]（+）。在负离子条件下，GaX_3 + HX（X = Cl，Br或I）溶液中生成[GaX_4]（-）和[GaX_3（OH）]（-），沿着生成Ga-2和Ga-3物种，特别是[（GaX_3）（2）（OH）]（-）。InX 3 + HX溶液显示[InX 4]（-）和[In 2X 7]（-）。ES-MS数据也报道了镓的混合卤化物溶液，并为含有额外的配体F-，NO3-或NCS-的GaCl 3的溶液。在InI 3水溶液中加入该冠醚，用ES-MS检测到络合阳离子[InI 2（18-crown-6）]（+）和[InI（OH）（18-crown-6）]（+）。(C)1998年Elsevier Science S.A.

Electrospray mass spectrometric data for acidic gallium trihalide solutions, GaX3 (X = Cl or Br), reveal the unipositive ions [GaX2](+), [GaX(OH)](+) and [Ga(OH)(2)](+) often associated with molecules of H2O or MeCN from the solvent phase. GaI3 solutions yield mainly the solvated [Ga(OH)(2)](+) ion. Solutions of InX3 produce the [InX2](+) cations in association with solvent molecules; the predominant hydrolysed cation is solvated [InO](+). Under negative ion conditions, solutions of GaX3 + HX (X = Cl, Br or I) give rise to [GaX4](-) and [GaX3(OH)](-), along with Ga-2 and Ga-3 species, particularly [(GaX3)(2)(OH)](-). Solutions of InX3 + HX show [InX4](-) and [In2X7](-). ES-MS data are also reported for mixed halide solutions of gallium, and for solutions of GaCl3 containing the additional ligands F-, NO3- or NCS-. Complex cations [InI2(18-crown-6)](+) and [InI(OH)(18-crown-6)](+) were detected by ES-MS on adding this crown ether to aqueous InI3 solution. (C) 1998 Elsevier Science S.A. All rights reserved.
