(2E)-1-(1,3-Benzodioxol-5-yl)-3-(2-bromophenyl)prop-2-en-1-one

Abstract

The mol-ecule of the title compound, C16H11BrO 3, is essentially planar with a maximum deviation of 0.178 (4) Å and the configuration of the keto group with respect to the olefinic double bond is typically s-cis. In the crystal structure, inter-molecular Br⋯O inter-actions [3.187 (3)Å] give rise to chains parallel to the b axis. Adjacent chains are further linked along the a axis by C - H⋯π inter-actions. The crystal studied was a racemic twin with a 0.595 (13):0.405 (13) ratio.
