Synthesis and crystal structure of (2E)-1-[3,5-bis(benzyloxy)phenyl]-3-(4-ethoxyphenyl)prop-2-en-1-one

Abstract

In the title compound, C31H28O4, the phenyl rings of the chalcone unit subtend a dihedral angle of 26.43 (10)°. The phenyl rings of the pendant benzyloxy groups are orientated at 75.57 (13) and 75.70 (10)° with respect to their attached ring. In the crystal, weak C—H...O and C—H...π interactions link the molecules. The intermolecular interactions were quantified and analysed using Hirshfeld surface analysis, which showed a breakdown into H...H (49.8%), H...C/C...H (33.8%) and H...O/O...H (13.6%) interactions with other types making negligible contributions.
