(E)-3-(2,3-Dimethoxyphenyl)-1-(2-hydroxy-4-methoxyphenyl)prop-2-en-1-one

The mol-ecular conformation of the title compound, C(18)H(18)O(5), is stabilized by a strong intra-molecular hydrogen bond between the hydroxyl and carbonyl groups. The C=C double bond displays an E configuration while the carbonyl group shows an S-cis configuration relative to the double bond. The dihedral angle between the two rings is 15.0 (1)°.

(E)-3-(4-Heptyloxyphenyl)-1-phenylprop-2-en-1-one

In the title compound, C22H26O2, the aromatic rings are inclined to one another by 8.39 (9)° and the mol-ecule has an E conformation about the C=C bond. In the crystal, mol-ecules stack head-to-tail along the b-axis direction. They are linked by very weak C-H⋯O contacts, forming C(4) chains along [100]. Two chains are linked by a pair of very weak C-H⋯O contacts, enclosing inversion-dimeric R 2...

In the title mol-ecule, C(22)H(15)Cl(2)NO, the dihedral angles between the central aromatic ring and the N- and C=O-bonded rings are 43.13 (13) and 0.80 (14)°, respectively. The dihedral angle between the terminal rings is 43.15 (14)°. The major twist occurs about the C(ar)-N bond [C(ar)-C(ar)-N=C = 42.3 (4)°; ar is aromatic].
