Figure 2
A view along the b axis of part of one double chain of water molecules and Br− ions running along the a direction. The double chain has alternating smaller and larger hydrogen-bonded rings denoted by the graph-set symbols R24(8) and R46(12). [Symmetry codes: (i) −x, 1 − y, 1 − z; (iii) −x, 1 − y, −z; (iv) 1 + x, y, 1 + z; (v) 1 − x, 1 − y, 1 − z. |
