    Crystal structure and Hirshfeld surface analysis of (2E)-1-(3-bromo­phen­yl)-3-(4-fluoro­phen­yl)prop-2-en-1-one
    (2019) Atioğlu, Zeliha; Bindya, S.; Akkurt, Mehmet; Kumar, C. S. Chidan
    In the title compound, C15H10BrFO, the mol­ecular structure consists of a 3-bromo­phenyl ring and a 4-fluoro­phenyl ring linked via a prop-2-en-1-one spacer. The 3-bromophenyl and 4-fluorophenyl rings make a dihedral angle of 48.90?(15)°. The mol­ecule has an E configuration about the C=C bond and the carbonyl group is syn with respect to the C=C bond. In the crystal, mol­ecules are linked by C—H?? inter­actions between the bromo­phenyl and fluoro­phenyl rings of mol­ecules, resulting in a two-dimensional layered structure parallel to the ab plane. The mol­ecular packing is stabilized by weak Br?H and F?H contacts, one of which is on the one side of each layer, and the second is on the other. The inter­molecular inter­actions in the crystal packing were further analysed using Hirshfeld surface analysis, which indicates that the most significant contacts are Cl?H/H?Cl (20.8%), followed by C?H/H?C (31.1%), H?H (21.7%), Br?H/H?Br (14.2%), F?H/H?F (9.8%), O?H/H?O (9.7%).
