(E)-3-(2,3-Dichlorophenyl)-1-(2-methoxyphenyl)prop-2-en-1-one

Abstract

In the title compound, C16H12Cl2O2, the olefinic double bond adopts an E configuration. The molecule is non-planar, as shown by the dihedral angle of 15.40 (19)° between the 2,3-dichlorophenyl ring and the 2-methoxyphenyl ring. In the crystal, molecules are linked via weak C—H...O hydrogen bonds, forming zigzag chains propagating along the c axis.
