Br 3 FOS, a chalcone derivative, are in the normal ranges. The bromo substituents at the central C-C single bond are trans to each other.
The title compound, C 15 H 8 Br 2 Cl 3 FO, crystallizes with two independent molecules in the asymmetric unit. The dihedral angle between the two benzene rings is 58.0 (2) in one molecule and 52.0 (2) in the other. A C-HΓ Γ ΓCl intramolecular interaction is observed. The crystal packing is stabilize
In the title molecule, C~16~H~11~Br~3~Cl~2~O~2~, the chain Br atoms are in __trans__ positions [BrβCβCβBr torsion angle is 179.0β (2)Β°]. The two benzene rings make a dihedral angle of 39.54β (15)Β°. The crystal packing is determined by van der Waals forces; some weak ΟβΟ interactions between the benzen
