    In the title compound, C(29)H(40)O(3), the enone moiety adopts an s-cis conformation. The dihedral angle between the benzene rings is 4.33 (5)° The least-squares mean line through the tetra-decyl side chain forms a dihedral angle of 83.99 (7)° with the normal to the attached benzene ring. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds involving the keto and the hy-droxy O atoms form ribbons along [-41-1]. The crystal structure also features C-H⋯π inter-actions.

    PMID: 23125701 DOI: 10.1107/S1600536812038007
    In the title compound, C(21)H(24)O(3), the enone moiety adopts an s-cis conformation and the dihedral angle between the benzene rings is 12.89 (6)°. The hex-yloxy tail adopts an extended conformation. In the crystal, inversion dimers are linked by pairs of O-H⋯O hydrogen bonds and pairs of C-H⋯O inter-actions, forming two R(2) (2)(7) and one R(2) (2)(10) loops. The dimers are then arranged into sheets lying parallel to (201) and weak C-H⋯π inter-actions consolidate the packing.

    In the title compound, C(25)H(32)O(3), the enone group adopts an s-cis conformation. The alk-oxy chain is in an all-trans conformation. The dihedral angle between the benzene rings is 7.86 (5)°. In the crystal, mol-ecules 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 mol-ecules [largest deviation for an atom being 0.4737 (12) Å for the terminal C atom of the alk-oxy chain] are arranged in sheets parallel to (20-1). Weak C-H⋯π inter-actions are also observed.
