Figure 3
Structural comparison between KCl·H2O and the B1 phase of KCl. (a) KCl·H2O viewed along the b axis. (b) KCl viewed along the b axis. Bird views for (c) KCl·H2O and (d) KCl. Purple, green and red balls represent K, Cl and O atoms, respectively. H atoms of water molecules are not shown for clarity. Black lines indicate K–Cl chains with K—Cl distances shorter than 3.2 Å almost perpendicular to the b axis. Red lines show K–Cl chains along the b axis. The blue shaded areas represent a space elongating along the b axis of KCl·H2O, where water molecules are located. |
