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

In the title compound, C(21)H(24)O(3), 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) Å, and adopts a trans conformation throughout. An intra­molecular O—H⋯O 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⋯π inter­actions and short C⋯O [3.376 (2) Å] contacts.
