Figure 7
Extracted structure components in MgCl2·7H2O. (a) View along the b axis. Layers formed by Cl and O atoms, which are almost perpendicular to n1, are coloured yellow. (b) Extracted single layer specified in (a). (c) View along n1 direction. Red/blue, deep/light green and orange balls represent oxygen, chlorine, and magnesium atoms, respectively. Oxygen and chlorine atoms in different layers are distinguished by different colouring in (c). Atoms in the same layers are connected by red/blue lines. Hydrogen atoms are omitted for clarity. The inter/intralayer displacements between anion sites are described as average in the periodicity from the single-crystal X-ray diffraction at 2.5 GPa and 298 K for MgCl2·7H2O in (a) and (c). |
