(E)-3-(4-Decyl-oxyphen-yl)-1-(2-hydroxy-phen-yl)prop-2-en-1-one.

In the title compound, C(25)H(32)O(3), the enone group is in an s-cis configuration. The dihedral angle between the benzene rings is 8.84 (7)°. An intra-molecular O-H⋯O inter-action between the keto and hydr-oxy groups forms an S(6) ring motif. Inter-molecular C-H⋯O inter-actions link the mol-ecules into supra-molecular chains along the c axis which are subsequently stacked down the b axis; the crystal structure is further consolidated by C-H⋯π inter-actions.
