Abstract

In the title compound, C(26)H(27)BrN(2)O, the piperidine ring has a chair conformation and all ring substituents occupy equatorial positions, apart from the double-bonded N atom, which occupies a bis-ectional position. The dihedral angle formed between the phenyl rings is 61.18 (19)°, and the phenyl rings form dihedral angles of 49.78 (19) and 69.2 (18)° with the bromo-benzene ring. The latter is coplanar with the meth-oxy(methyl-idene)amine fragment [N-O-C-C torsion angle = -171.7 (2)°]. Linear supra-molecular chains, approximately along [112], sustained by C-H⋯π inter-actions, feature in the crystal packing.

摘要

在标题化合物C(26)H(27)BrN(2)O中,哌啶环呈椅式构象,除占据双连接N原子的平分位置外,所有环取代基均占据赤道位置。苯环之间形成的二面角为61.18 (19)°,且苯环与溴苯环形成的二面角分别为49.78 (19)°和69.2 (18)°。后者与甲氧基(亚甲基)胺片段共面 [N-O-C-C扭转角 = -171.7 (2)°]。由C-H⋯π相互作用维持的近似沿[112]方向的线性超分子链是晶体堆积的特征。
