Figure 33
4,4′-Dichlorobenzophenone – projection down [010] of the structures at 295 K (upper) and 164 K (lower). The carbonyl bond points alternately in and out of the page. The high- and low-temperature structures are formally related by a shift of the middle vertical sheet of molecules by c/2. The same unit cell has been retained for the two structures with space group changed from C2/c (295 K) to I2/c (164 K). The low-temperature C2/c cell is shown by thin lines.
