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.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
