(2E)-3-(2-Bromo-phen-yl)-1-(4,4''-difluoro-5'-meth-oxy-1,1':3',1''-terphenyl-4'-yl)prop-2-en-1-one.

ABSTRACT: In the title compound, C(28)H(19)BrF(2)O(2), the central benzene ring makes dihedral angles of 62.51?(18), 46.23?(18) and 48.19?(18)° with the bromo-substituted benzene ring and two terminal fluoro-substituted benzene rings, respectively. In the crystal, mol-ecules are linked by C-H?F hydrogen bonds into infinite chains along [110]. Weak C-H?? and ?-? inter-actions [centroid-centroid distance = 3.683?(2)?Å] also occur and short inter-molecular F?F contacts [2.833?(4)?Å] are observed.
