Protonation of an NNNN-macrocycle chelated gallium(I) cation provides a rare dicationic gallium(III) hydride. This process is easily reversed by treatment of the Brønsted acidic (pK_a=24.5) hydride with a neutral base. Similar facile redox cycling was not observed for analogous aluminium, indium, or thallium systems.

Brønsted 酸性氢化镓：NNNN 大环支持的 [GaI]+ 和 [GaIIIH]2+ 的简单相互转化

NNNN-大环螯合镓 (I) 阳离子的质子化提供了一种稀有的双阳离子氢化镓 (III)。_{这个过程很容易通过用}中性碱处理 Brønsted 酸性 (p Ka = 24.5) 氢化物来逆转。对于类似的铝、铟或铊系统，没有观察到类似的简单氧化还原循环。
