Figure 5
A polyhedral representation of MgCl2·4H2O (top) and FeBr2·4H2O (bottom; data from Waizumi et al., 1992BB13). The horizontal layers of octa­hedra are essentially identical in the two structures. Stacking of the layers in MgCl2·4H2O can be described as an ABAB sequence, compared with an AAA sequence in FeBr2·4H2O.
