Figure 8
(a) A wider view of the structure of the high-pressure phase of MgSO4·5H2O, showing the hydrogen bonding (dashed rods) between neighbouring Mg(H2O)5SO4 ion pairs. (b) A view of the packing in the ac plane, emphasizing the hydrogen-bonded chains of MgO6 octahedra, linked by Ow5—H5b⋯Ow3, along the a axis. The outline of one unit cell is shown by solid black lines. Symmetry codes: (i) + x, − y, z; (ii) x − , − y, z; (iii) − x, + y, + z; (iv) 1 − x, −y, + z. |
