(E)-1-(4-Decyloxyphenyl)-3-(2-hydroxyphenyl)prop-2-en-1-one

Abstract

Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.001 Å; R factor = 0.050; wR factor = 0.160; data-to-parameter ratio = 32.7.In the title compound, C 25 H 32 O 3 , the enone group adopts an scis conformation. The alkoxy chain is in an all-trans conformation. The dihedral angle between the benzene rings is 7. 86 (5) . In the crystal, molecules are connected by pairs of O-HÁ Á ÁO hydrogen bonds, forming inversion dimers and giving R 2 2 (10) rings. Within these dimers, weak C-HÁ Á ÁO hydrogen bonds form two R 2 2 (7) rings. In the crystal, the approximately planar molecules [largest deviation for an atom being 0.4737 (12) Å for the terminal C atom of the alkoxy chain] are arranged in sheets parallel to (201). Weak C-HÁ Á Á interactions are also observed. Related literature
