(E)-1-(Benzo[d][1,3]dioxol-5-yl)-3-(2,3-di-chloro-phen-yl)prop-2-en-1-one

摘要

In the title compound, C16H10Cl2O3, the olefinic double bond adopts an E conformation [C—C C—C torsion angle = 172.9 (3)]. The dihedral angle between the benzodioxole and dichlorobenzene rings is 5.57 (9). In the crystal, molecules are linked by weak C—HO and C—HCl hydrogen bonds, forming chains propagating along the c-axis direction.
