Figure 4
Drawings of the 4-10COOH packing in the planes (130), (21[\overline 5]) and ([\overline 1]25). The F atoms are shown in green and the O atoms in red. The [3[\overline 1]1] vector points vertically upwards in each case; the vectors corresponding to translations within dimer layers are shown and identified below the drawings. The columns containing molecules E and F are marked with asterisks; the disorder is more obvious in (21[\overline 5]) and ([\overline 1]25) than in (310). Arrows indicate the alternating rows of regions with and without F atoms. If the drawing of the (130) plane were extended to the left or right the arrow shown would pass through ten CH2 groups before passing through another CF2 group. The pictures were drawn with the program SHELXTL-PC (Sheldrick, 1994BB21).
