(E)-3-(Biphenyl-4-yl)-1-(3-bromo-phen-yl)prop-2-en-1-one.

ABSTRACT: In the title compound, C(21)H(15)BrO, there are two planar rings connected through a conjugated double bond. As it crystallizes in a non-centrosymmetric space group it can be regarded as a good candidate for non-linear optical applications. The mol-ecule adopts an E configuration and the C-C=C-C torsion angle is 177.1?(4)°. The overall conformation of the compound may be described by the values of dihedral angles between the approximately planar parts. The terminal rings are twisted by an angle of 51.52?(9)°, while the biphenyl part is almost planar, the dihedral angle between the planes of the rings being 4.44?(17)°. The unit cell has one long dimension, above 35?Å, characteristic also of a majority of related compounds. The mol-ecules pack head-to-tail along this direction. C-H?? inter-actions are observed in the crystal structure.
