(2E)-3-[4-(Dimethylamino)phenyl]-1-(4-fluorophenyl)prop-2-en-1-one

Abstract

The mean planes of the two benzene rings in the title compound, C17H16FNO, are twisted slightly, making a dihedral angle of 7.8 (1)°. The prop-2-en-1-one group is also twisted slightly with a C—C—C—O torsion angle of −11.6 (3)°. In the crystal, weak inter­molecular C—H⋯O inter­actions link pairs of mol­ecules, forming centrosymmetric dimers.

(E)-3-(3,4-Dimethoxyphenyl)-1-(2-hydroxyphenyl)prop-2-en-1-one

“…The mean plane of the prop-2-en-1-one group, the active site in this molecule, makes angles of 3.6 (0)° and 2.6 (7)°, respectively, with the hydroxyphenyl and dimethoxyphenyl rings. Bond lengths and angles are normal (Allen et al, 1987) and corespond to those observed in related compounds (Butcher et al, 2006;Cao et al, 2005;Harrison et al, 2007;Jasinski et al, 2010Jasinski et al, , 2011aJasinski et al, , 2011bNgaini et al, 2009;Radha Krishna et al, 2005;Sharma et al, 1997;Wu et al, 2005).
