(E)-1-(4-Decyl­oxyphen­yl)-3-(2-hy­droxy­phen­yl)prop-2-en-1-one

In the title compound, C(25)H(32)O(3), the enone group adopts an s-cis conformation. The alk­oxy chain is in an all-trans conformation. The dihedral angle between the benzene rings is 7.86 (5)°. In the crystal, mol­ecules are connected by pairs of O—H⋯O hydrogen bonds, forming inversion dimers and giving R (2) (2)(10) rings. Within these dimers, weak C—H⋯O hydrogen bonds form two R (2) (2)(7) rings. In the crystal, the approximately planar mol­ecules [largest deviation for an atom being 0.4737 (12) Å for the terminal C atom of the alk­oxy chain] are arranged in sheets parallel to (20-1). Weak C—H⋯π inter­actions are also observed.
