In the first observation of triply charged metal ions microsolvated by protic ligands, gas-phase complexes of 11 different metal trications with diacetone alcohol were generated using electrospray ionization. These species were found to exist for at least five to eight ligands, depending on the metal. For smaller sizes, charge reduction to dications occurs spontaneously via dissociative proton transfer. This is the largest minimum size reported for any multiply charged metal cation/ligand pair.
在对质子配体微溶剂化的三价金属离子的首次观察中，使用电喷雾电离产生了11种不同金属三价阳离子与双丙酮醇的气相配合物。发现这些物种根据金属的不同，至少存在五到八个配体。对于较小尺寸的物种，通过离解质子转移会自发地发生电荷还原为二价阳离子的情况。这是所报道的任何多电荷金属阳离子/配体对中最大的最小尺寸。
