![]() Herein, we present the crystal and molecular structure of (I). Therefore, it is important to determine the crystal structure. ![]() This high reactivity and the difference in the molecular conformation of resulting polymer in the solid state are considered to be caused by the molecular arrangement in the crystal of MLG NCA. This video (which has no sound) gives a quick, visual overview of some of the main capabilities of CrystalMaker X, including advanced visualization, live pow. The title compound (MLG NCA), (I), was very reactive in the solid state among the examined NCAs, and the conformation of the resulting poly(MLG) was mainly the β structure, while the poly(MLG) obtained in the solution reaction is the α helix. However, when well-purified l-alanine NCA crystals were polymerized in acetonitrile solution or the solid state under strict moisture-free conditions, the reactivity in the solid state seemed similar to that in acetonitrile (Kanazawa et al., 2006 ▸). Unlimited numbers of chemical occupants per. We found that l-leucine NCA was the most reactive in the solid state polymerization among the examined amino acid NCAs, and the solution polymerization reactivity of l-alanine NCA in acetonitrile seemed to be more reactive than that in the solid state. Build any crystal structure, using the Crystal Editor: spacegroup, unit cell parameters plus asymmetric unit. We have reported the crystal structures of glycine NCA (Kanazawa et al., 1976 a ▸) and l-alanine NCA (Kanazawa et al., 1976 b ▸), and found the polymerization rate depended on the crystal structure (Kanazawa & Kawai, 1980 ▸).
