Powder diffraction pattern of (a) 1,2-dichlorotrifluoroethane, HCFC-123a, collected at 60 K, corresponding to a hexagonal unit cell with a = 3.998 (1), c = 6.5199 Å, and (b) 2-chloro-1,1,1,2-tetrafluoroethane, HCFC-124, collected at 62 K, corresponding to a hexagonal unit cell with a = 4.0436 (1), c = 6.6127 (1) Å. The peak intensities for this compound were poorly reproducible showing marked fluctuations owing to granularity of the sample. Both data sets were collected on BM16 at the ESRF with a wavelength of 0.401340 (2) Å. |
