Figure 7
Water channel structures of (a) CaSO4·0.5H2O, viewing direction ([\overline {10}_{\prime} ]1[_{\prime} ]10), and (b) CaSO4·0.625H2O, viewing direction ([\bar 310]). Ca ions and SO4 groups are omitted. Different colors of O atoms indicate the different relative positions of the water molecules. In (b) these water molecules are systematically shifted compared with the water positions of the unchanged channel in the middle of the picture.
