三元组F3B·NCX·NCM（X和M为卤素原子）中的路易斯酸碱相互作用与卤素键之间存在异常协同效应，其中F3B与NCX之间的强路易斯酸碱相互作用比NCX与NCM之间的弱卤素键具有更大的增强作用。这与传统的合作效应形成鲜明对比。有趣的是，碱金属取代基以及较重的卤素原子在增强F3B·NCX相互作用方面比NCX·NCM发挥更显着的作用，特别是碱金属取代基使异常协同效应成为传统的协同效应。
An abnormal synergistic effect was found between the Lewis acid–base interaction and halogen bond in triads F3B···NCX···NCM (X and M are halogen atoms), where the strong Lewis acid–base interaction between F3B and NCX has a larger enhancement than the weak halogen bond between NCX and NCM. This is in contrast with the traditional cooperative effect. It is interesting that the alkali-metal substituent as well as the heavier halogen atom play a more remarkable role in the enhancement of the interaction F3B···NCX than that of NCX···NCM, particularly, the alkali-metal substituent makes the abnormal synergistic effect be the traditional cooperative one.
