RESUMO
The synthesis, crystal structure and spectroscopic analysis of (E)-1-(2,3-di-hydro-benzo[b][1,4]dioxin-6-yl)-3-(4-chloro-phen-yl)prop-2-en-1-one (C17H13ClO3), a substituted chalcone, are described. The overall geometry of the mol-ecule is largely planar (r.m.s. deviation = 0.1742â Å), but slightly kinked, leading to a dihedral angle between the planes of the benzene rings at either side of the mol-ecule of 8.31â (9)°. In the crystal, only weak inter-actions determine the packing motifs. These include C-Hâ¯O and C-Hâ¯Cl hydrogen bonds and π-π overlap of aromatic rings.
