(E)-3-[4-(Dec-yloxy)phen-yl]-1-(4-hydroxy-phen-yl)prop-2-en-1-one.

ABSTRACT: 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 crosslinked along the b axis via C-H?O hydrogen bonds, forming a two-dimensional network parallel to the ab plane.

Project description:In the title compound, C(21)H(24)O(3), the conformation of the enone group is s-cis. The benzene rings are inclined at an angle of 7.9?(1)°. The alk-oxy tail is planar, with a maximum deviation from the least-squares plane of 0.009?(2)?Å, and adopts a trans conformation throughout. An intra-molecular O-H?O inter-action between the keto and hydr-oxy groups forms S(6) ring motifs. In the crystal, mol-ecules are arranged in a head-to-tail manner down the a axis and are subsequently stacked along the b axis, forming mol-ecular sheets parallel to the ab plane. The crystal structure is further stabilized by weak C-H?? inter-actions and short C?O [3.376?(2)?Å] contacts.

(E)-3-[4-(Dodec-yloxy)phen-yl]-1-(2-hydroxy-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C(27)H(36)O(3), the asymmetric unit consists of two crystallographically independent mol-ecules. The aromatic rings form dihedral angles of 17.1?(2) and 17.6?(2)° in the two molecules. In both mol-ecules, the enone groups adopt an s-cis conformation and the alkoxyl chains are in trans conformations curving out of the zigzag plane. Intra-molecular O-H?O hydrogen bonds involving the keto and hydr-oxy groups generate S(6) ring motifs. The mol-ecules are stacked alternately in a head-to-tail fashion along the a axis and the crystal structure is stabilized by weak C-H?? inter-actions. The crystal studied was a non-merohedral twin, the ratio of components being 0.788?(2):0.212?(2).
