A solution of potassium hydroxide (5%, 5 ml) was added slowly with stirring to a mixture of biphenyl aldehyde (1.8 g, 0.01 mol) and 4-fluoroacetophenone (1.38 g, 0.01 mol) in ethanol (15 ml). The mixture was stirred at room temperature for 6 h. The precipitated solid was filtered, washed with cold ethanol, dried and recrystallized from ethanol (yield: 83%; m.p.:405–407 K). Analysis for C21H15FO: Found (Calculated): C: 83.30 (83.42); H: 4.91% (5.00%).
In the absence of any anomalous scatterer, the Flack (1983) parameter is meaningless and therefore, Friedel pairs had been merged prior to refinement. H atoms were found in a difference map, but they were refined using a riding model with C—H = 0.95Å and Uiso(H) = 1.2Ueq(C).
Chalcones (1,3-diaryl-2-propen-1-ones), belonging to the flavonoid family is one of the major class of natural products which have been recently subjects of great interest for their interesting pharmacological activities. Chalcones have been reported to possess many useful properties, including anti-inflammatory, antimicrobial, antifungal, antioxidant, cytotoxic, antitumor and anticancer activities. Among several organic compounds reported for NLO property, chalcone derivatives are noticeable materials for their excellent blue light transmittance and good crystallizability. We have synthesized a new chalcone.
The title compound, C21H15FO, crystallized with two molecules in the asymmetric unit, which differ only in the sign of their torsion angles. A least-squares fit of all non H atoms of molecule one with the inverted molecule two gives an r.m.s. deviation of 0.022 Å. Nevertheless, the two molecules are not related by any crystallographic symmetry element (Fig. 2). The dihedral angle between the two phenyl rings of the biphenyl unit is 3.0 (2)% and 2.1 (2)°, respectively.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Chalcones (1,3-diaryl-2-propen-1-ones), belonging to the flavonoid family is one of the major class of natural products which have been recently subjects of great interest for their interesting pharmacological activities. Chalcones have been reported to possess many useful properties, including anti-inflammatory, antimicrobial, antifungal, antioxidant, cytotoxic, antitumor and anticancer activities. Among several organic compounds reported for NLO property, chalcone derivatives are noticeable materials for their excellent blue light transmittance and good crystallizability. We have synthesized a new chalcone.
The title compound, C21H15FO, crystallized with two molecules in the asymmetric unit, which differ only in the sign of their torsion angles. A least-squares fit of all non H atoms of molecule one with the inverted molecule two gives an r.m.s. deviation of 0.022 Å. Nevertheless, the two molecules are not related by any crystallographic symmetry element (Fig. 2). The dihedral angle between the two phenyl rings of the biphenyl unit is 3.0 (2)% and 2.1 (2)°, respectively.
