三-1，10-菲啉金属二价离子[（phen）3 M]2+（其中M = Ni和Mg）与四苯基硼酸根阴离子之间的气相离子-离子反应产生离子对{[（phen）3 M]2+[BPh 4]-}+。离子对在失去phen配体后进行金属转移，得到有机金属配合物[（phen）2 M（Ph）]+。DFT计算，用于确定金属转移反应和水解反应的能量障碍，是完全符合实验结果。
Gas-phase ion-ion reactions between tris-1,10-phenantholine metal dications, [(phen)3M]2+ (where M = Ni and Mg), and the tetraphenylborate anion yield the ion-pairs {[(phen)3M]2+[BPh4]−}+. The ion-pairs undergo transmetalation upon loss of a phen ligand to give the organometallic complexes [(phen)2M(Ph)]+. DFT calculations, used to determine the energy barriers for the transmetalation reactions and the hydrolysis reactions, are entirely consistent with the experimental results.
