solutions as GaGa bonded gallium(II) species stabilised by halide ligands in the form of the complex anions Ga2X6 2− (X=Cl, Br or I) whose formation and reactivity are discussed. Gallium(I) compounds and mixed valence compounds of gallium react vigorously with water, converting any Ga+ ions into Ga(III) products. Indium(I) is more tolerant of water, so that perchlorate and other non-complexing aqueous media

镓可作为GaGa键合的
镓(II)物种以卤化物
配体形式稳定,并以络合物阴离子Ga 2 X 6 2-(X = Cl,Br或I)的形式存在,并在其中讨论了其形成和反应性。
镓(I)化合物和
镓的混合价化合物与
水剧烈反应,将任何Ga +离子转化为Ga(III)产物。
铟(I)更耐
水,因此
高氯酸盐和其他非络合
水性介质可以负载高达10 -3 mol -1的In +离子,然后歧化为In(0)和In(III)。亚
铟浓度约为10 -1 mol l -1在卤代酸溶液中,特别是在
溴化氢溴化氢中,可得到稀释的红色固体InBr。光谱数据表明,该前体是能够分解为In(I)和In(III)产物的In(II)In(II)
溴化物络合物(可能是In 2 Br 6 2-)。
