(3E)-3-[4-(Dimethylamino)phenyl]-1-(4-hydroxyphenyl)prop-2-en-1-one

Abstract

The asymmetric unit of the title compound, C17H 17NO2, contains two crystallographically independent molecules. Both molecules adopt a trans configuration about the C=C bond, with the C-C=C-C fragments in the two molecules twisted in opposite directions [torsion angles of 174.2 (2) and-175.8 (2)°]. The two benzene rings in each of the molecules make dihedral angles of 20.21 (6) and 48.64 (4)°. In the crystal, adjacent molecules are linked by O-H⋯O hydrogen bonds into infinite polymeric chains.
