Abstract

In the title compound, C(15)H(15)NO, the amide fragment has an anti conformation. The central amide group is tilted with respect to the benzoyl ring, forming a dihedral angle of 32.3 (5)°. The benzoyl and aniline rings make a dihedral angle of 59.6 (5)°. Mol-ecules are linked into infinite supra-molecular chains via N-H⋯O hydrogen bonds. The mol-ecule is disordered so that the aromatic rings are disposed across a twofold axis with equal occupancies.

摘要

在标题化合物C(15)H(15)NO中,酰胺片段呈反式构象。中心酰胺基团相对于苯甲酰环倾斜,形成32.3 (5)°的二面角。苯甲酰环和苯胺环形成59.6 (5)°的二面角。分子通过N-H⋯O氢键连接成无限的超分子链。该分子无序,使得芳香环以相等占有率分布在一个二重轴上。
