(2E)-3-(4-Bromophenyl)-1-(3-chlorophenyl)prop-2-en-1-one

Abstract

In the title compound, C15H10BrClO, the dihedral angle between mean planes of the bromo- and chloro-substituted benzene rings is 46.2 (2)° compared to 45.20 (9)° in the structure with the Cl substituent in the meta position of the aromatic ring. The dihedral angles between the mean plane of the prop-2-ene-1-one group and the mean planes of the 4-bromo­phenyl and 3-chloro­phenyl rings are 28.7 (5) and 24.2 (4)°, respectively. In the crystal, weak inter­molecular C—H⋯π inter­actions occur.

“…The molecular structure of 1-(2-hydroxy-5-methylphenyl)-3-(3-methylthiophen-2-yl)prop-2-en-1-one, consists of a phenyl ring and a thiophen ring attached to a propanone chain at 1,3-position. The bond lengths C7-C9, C9-O10, C9-C11, C11-C12, C12-C13 and bond angles C7-C9-O10, O10-C9-C11 are in good agreement with those of the similar compounds reported earlier (Jasinski et al, 2009;Jasinski et al, 2010). The torsion angle for C12-C13-C17-C18 is -1.71°…”

“…Chalcones are finding applications as organic non-linear optical materials (NLO) due to their good SHG conversion efficiencies (Sarojini et al, 2006). Hence, in continuation with our synthesis and crystal structure determinations of similar compounds (Jasinski et al, 2009;Jasinski et al, 2010) and also owing to the importance of these flavanoid analogs, this new bromo-chloro substituted chalcone, C 15 H 10 BrClO, is synthesized and its crystal structure is reported.…”
