Comment
For an introduction, see Fischeret al.(2007a).
[image:1.610.223.429.278.388.2]The title chalcone, (I), was prepared by treating 4-chloro-acetophenone with biphenyl-4-carbaldehyde in the presence of KOH.
Fig. 1 shows the molecular structure. The geometry of the molecule is unexceptional; its geometry deviates significantly from planarity [dihedral angles 4.42 (16)within the biphenyl
group and 48.85 (16) between the C10–C15 ring and the
chlorophenyl ring].
The compound is isostructural with the corresponding bromo compound (Fischeret al., 2007b).
Experimental
4-Chloroacetophenone (1.54 g, 0.01 mol) in methanol (20 ml) was mixed with biphenyl-4-carbaldehyde (1.82 g, 0.01 mol) and the
Figure 1
[image:1.610.208.459.592.723.2]mixture was treated with a 30% potassium hydroxide solution (3 ml) at 278 K. The reaction mixture was then brought to room tempera-ture and stirred for 3 h. The precipitated solid was filtered off, washed with water, dried and recrytallized from acetone (m.p. 439–441 K). Analysis (%) for C21H15ClO found (calculated): C 76.83 (76.94), H
4.86 (4.92).

H atoms were placed at calculated positions and refined as riding on the respective carrier atom, with C—H = 0.93 A˚ andUiso(H) =
1.2Ueq(C). The structure appears to exhibit turbostratic disorder,
which could be detected in precession photographs that were
simu-lated from the CCD data. The disorder was accounted for in the data processing withEVALCCD(Duisenberget al., 2003).

Special details
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.
