The asymmetric unit of the title compound, C(17)H(17)NO(2), contains two crystallographically independent mol-ecules. Both mol-ecules adopt a trans configuration about the C=C bond, with the C-C=C-C fragments in the two mol-ecules twisted in opposite directions [torsion angles of 174.2 (2) and -175.8 (2)°]. The two benzene rings in each of the mol-ecules make dihedral angles of 20.21 (6) and 48.64 (4)°. In the crystal, adjacent mol-ecules are linked by O-H⋯O hydrogen bonds into infinite polymeric chains.
标题化合物C(17)H(17)NO(2)的不对称单元包含两个晶体学独立的分子。两个分子中C=C键均呈反式构型，两个分子中的C-C=C-C片段扭转方向相反[扭转角分别为174.2 (2)°和 -175.8 (2)°]。每个分子中的两个苯环形成的二面角分别为20.21 (6)°和48.64 (4)°。在晶体中，相邻分子通过O-H⋯O氢键连接成无限的聚合物链。
