Two independent mol-ecules (A and B) comprise the asymmetric unit of the title compound, C(26)H(28)ClN, with the inverted form of B almost superimposable upon A. Each piperidine ring has a chair conformation and the chloro substituent is anti to the piperidine N atom. Each of two aromatic rings, the benzyl residue and one methyl group substituents occupies an equatorial position, and the second methyl substituent occupies an axial position. The dihedral angle formed between the chloro-benzene ring and the flanking phenyl rings in mol-ecule A are 84.24 (9) and 24.85 (8)°; the equivalent angles for mol-ecule B are 79.97 (9) and 28.33 (9)°. In the crystal, the A and B mol-ecules are connected by C-H⋯Cl and C-H⋯π inter-actions, forming a supra-molecular chain along [101].
两个独立分子（A和B）构成了标题化合物C₂₆H₂₈ClN的不对称单元，B的反式结构几乎与A重叠。每个哌啶环呈椅式构象，氯取代基与哌啶氮原子呈反式。两个芳环、苄基残基和一个甲基取代基中的每一个都占据赤道位置，第二个甲基取代基占据轴向位置。分子A中氯苯环与侧翼苯环之间形成的二面角分别为84.24 (9)°和24.85 (8)°；分子B的等效角度为79.97 (9)°和28.33 (9)°。在晶体中，A和B分子通过C—H⋯Cl和C—H⋯π相互作用相连，沿[101]方向形成超分子链。
