Abstract

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.
