Racemic crystal
WebApr 10, 2024 · To our knowledge, this is the first report of a racemic crystal structure of A-form DNA. Figure 2. Asymmetric units of D/L-d (CCCGGG)2 in two racemic crystal forms: … WebNo experimental evidence was found for other phases, but considerable efforts to grow a single crystal of the racemic compound were fruitless, so the structure had to be solved from powder X-ray diffraction. Indexing the powder pattern suggested a Pbca space group and so this space group was searched more thoroughly using CrystalPredictor.
