(E)-1-[4-(Hexyloxy)phenyl]-3-(2-hydroxy-phenyl)prop-2-en-1-one

Abstract

In the title compound, C21H24O3, the enone moiety adopts an s-cis conformation and the dihedral angle between the benzene rings is 12.89 (6)°. The hexyloxy 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 interactions, 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 interactions consolidate the packing.
