Figure 4
Structure of MgCl2·7H2O in configuration 1 optimized by DFT calculation. The close-up view of the hydrogen-bonded chain formed by water molecules is shown in the right panel. The hydrogen bonds with d(H⋯O) shorter than 2 Å are described by dashed lines. Interatomic H6A and O6 bond with d(H⋯O) = 2.16 Å are shown by dotted lines. |
