Solid-state NMR meets electron diffraction: determination of crystalline polymorphs of small organic microcrystalline samples
A combined approach of solid-state NMR and electron diffraction are demonstrated to determine the crystalline form of polycrystalline organic materials.
Distortion from a hypothetical higher-symmetry structure in 5,6-bis(9H-carbazol-9-yl)benzo[c][1,2,5]thiadiazole
The crystal structures of 5,6-bis(9H-carbazol-9-yl)benzo[c][1,2,5]thiadiazole (DCBT) and its hydrate were investigated using single-crystal X-ray analysis. The analysis of the crystal packing of DCBT revealed that the experimental triclinic structure could be described as a distortion from a hypothetical higher-symmetry monoclinic structure. The quantum chemical calculations of two possible monoclinic structures showed that the proposed structures are higher in energy by 5.4 and 10.1 kcal mol−1.
