Nonahydrated bromates

Besides the ethylsulfates and bromates, the trifluoromethanesulfates have been studied in detail (Harrowfield et al., 1983 Paiva Santos et al., 1985). Data from six three-dimensional X-ray structure analyses are available (table 34) the structures are similar to those of the ethylsulfate nonahydrates (fig. 139). Unit cell data, however, show an interesting and rather unexpected feature. While the cell volume decreases, the c-parameter increases significantly with the increasing atomic number, changing the ale ratio from 1.88 (La) to 1.71 (Lu) (Harrowfield et al., 1983).
