The absolute configuration of the title mol-ecular salt, C15H18N(+)·C8H6ClO3 (-), has been confirmed by resonant scattering. In the (R)-N-benzyl-1-phenyl-ethyl-ammonium cation, the phenyl rings are inclined to one another by 44.65 (7)°. In the crystal, the (R)-4-chloro-mandelate anions are linked via O-H⋯O hydrogen bonds and bridged by N-H⋯O hydrogen bonds involving the cations, forming chains along [010]. There are C-H⋯O hydrogen bonds present within the chains, which are linked via C-H⋯π inter-actions and a short Cl⋯Cl inter-action [3.193 (1) Å] forming a three-dimensional framework. The structure was refined as a two-component inversion twin giving a Flack parameter of 0.05 (4).
标题分子盐C15H18N(+)·C8H6ClO3 (-)的绝对构型已通过共振散射得到证实。在(R)-N-苄基-1-苯基乙铵阳离子中，苯环彼此倾斜44.65 (7)°。在晶体中，(R)-4-氯扁桃酸根阴离子通过O-H⋯O氢键相连，并通过涉及阳离子的N-H⋯O氢键桥连，沿[010]形成链状结构。链内存在C-H⋯O氢键，这些氢键通过C-H⋯π相互作用和短的Cl⋯Cl相互作用[3.193 (1) Å]相连，形成三维框架。该结构作为两组分倒易孪晶进行精修，得到的Flack参数为0.05 (4)。
