据报道，盐共晶的成分通过氢键和芳香族阴离子分子堆栈（π−–π 堆栈）组装而成。 U 形联吡啶和异香豆素羧酸自组装形成 5、6 和 10 组分聚集体，其中组分呈双和四重面对面堆叠。 DFT 计算支持 π−–π 堆栈，以帮助稳定盐共晶体。
Salt cocrystals with components that assemble by hydrogen bonds and aromatic anion–molecule stacks (π−–π stacks) are reported. U-shaped bipyridines and an isocoumarin carboxylic acid self-assemble to form 5-, 6-, and 10-component aggregates with components in double and quadruple face-to-face stacks. DFT calculations support the π−–π stacks to help stabilize the salt cocrystals.
