In the title compound, C(25)H(32)O(3), the enone group adopts an s-cis conformation. The alk-oxy unit is nearly planar and is in a trans conformation. The two benzene rings make a dihedral angle of 18.87 (9)°. In the crystal structure, mol-ecules are linked into chains running along the a axis by inter-molecular O-H⋯O hydrogen bonds involving the hydr-oxy and keto groups. The chains are crossli...

In the title compound, C18H17ClO, the dihedral angle between the benzene rings is 53.5 (1)°. The mean plane of the prop-2-en-1-one group is twisted by 24.5 (8) and 33.5 (3)° from the chloro- and propanyl-substituted rings, respectively.

The title compound, C(16)H(13)FO, adopts an E configuration with respect to the C=C bond of the propenone unit. The dihedral angle between the two benzene rings is 47.0 (5)°. Intra-molecular C-H⋯O hydrogen bonds generate an S(5) ring motif. In the crystal structure, mol-ecules are packed into columns along the c axis and the structure is stabilized by weak intra-molecular C-H⋯O hydrogen bonds a...

The crystal structure of the title compound, C(16)H(13)ClO(2) (II), (space group P2(1)/c,) is a polymorph of the structure, (I), reported by Harrison, Yathirajan, Sarojini, Narayana & Indira [Acta Cryst. (2006), E62, o1647-o1649] in the ortho-rhom-bic space group Pna2(1). The dihedral angle between the mean planes of the 4-chloro- and 4-meth-oxy-substituted benzene rings is 52.9 (1)° in (II) co...

In the title compound, C(23)H(19)FO(5)S(2), two of the phenyl ring C atoms and a sulfonyl O atom of the phenyl(methylsulfonyl) group are disordered over two positions with occupancies 0.522 (17):0.478 (17). The methyl-phenyl and fluoro-phenyl rings are essentially planar, with maximum deviations of 0.0059 (8) and 0.0047 (9) Å, respectively. The crystal packing is stabilized by C-H⋯F inter-actions.
