(E)-3-[4-(Hexyloxy)phenyl]-1-(2-hydroxyphenyl)prop-2-en-1-on

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 alkoxy tail is planar, with a maximum deviation from the least-squares plane of 0.009 (2) A˚ , and adopts a trans conformation throughout. An intramolecular O—HO interaction between the keto and hydroxy groups forms S(6) ring motifs. In the crystal, molecules are arranged in a head-to-tail manner down the a axis and are subsequently stacked along the b axis, forming molecular sheets parallel to the ab plane. The crystal structure is further stabilized by weak C—H interactions and short CO [3.376 (2) A˚ ] contacts
