In the title compound, C(25)H(26)ClN, the piperidine ring has a chair conformation with all ring substituents in equatorial positions. The dihedral angle formed between the chloro-benzene ring and the flanking phenyl rings are 74.91 (18) and 47.86 (17)°. The chloro substituent is anti to the piperidine N atom. In the crystal, centrosymmetrically related mol-ecules aggregate via π-π inter-actions occurring between chloro-benzene rings [centroid-centroid distance = 3.778 (2) Å] and these are linked into linear supra-molecular chains along the a axis by C-H⋯π inter-actions occurring between the phenyl rings.
在标题化合物C₂₅H₂₆ClN中,哌啶环呈椅式构象,所有环取代基均处于平伏位置。氯苯环与侧翼苯环之间形成的二面角分别为74.91 (18)°和47.86 (17)°。氯取代基与哌啶N原子呈反式。在晶体中,通过氯苯环之间发生的π-π相互作用(质心-质心距离 = 3.778 (2) Å),中心对称相关的分子聚集在一起,并且通过苯环之间发生的C-H⋯π相互作用沿着a轴连接成线性超分子链。
