(E)-3-[4-(Hex-yloxy)phen-yl]-1-(2-hydroxy-phen-yl)prop-2-en-1-one

Abstract

In the title compound, C21H24O3, the conformation of the enone group is s-cis. The benzene rings are inclined at an angle of 7.9 (1)°. The alk-oxy tail is planar, with a maximum deviation from the least-squares plane of 0.009 (2) Å, and adopts a trans conformation throughout. An intra-molecular O - H⋯O inter-action between the keto and hydr-oxy groups forms S(6) ring motifs. In the crystal, mol-ecules are arranged in a head-to-tail manner down the a axis and are subsequently stacked along the b axis, forming mol-ecular sheets parallel to the ab plane. The crystal structure is further stabilized by weak C - H⋯π inter-actions and short C⋯O [3.376 (2) Å] contacts.
