Benzoic acid forms hydrogen-bonded dimers in solution that further stack into tetramers by aromatic interactions. Both dimers and higher-order packing motifs are preserved in the resultant crystal structure. The finding hints at the significance in the hierarchy of intermolecular interactions in driving the self-association process in solution.

溶液中苯甲酸的高阶自组装

苯甲酸在溶液中形成氢键二聚体，并通过芳族相互作用进一步堆叠成四聚体。二聚体和高阶堆积图案都保留在所得的晶体结构中。该发现暗示了分子间相互作用的层次结构在驱动溶液中的自缔合过程中的重要性。
