Figure 17
Part of the crystal structure of (1) showing the formation of a hydrogen-bonded molecular ladder along [100] formed by cations and anions alone. For the sake of clarity, the water molecules and the H atoms bonded to C atoms are omitted. The O and N atoms marked with an asterisk (*), a hash (#) or a dollar sign ($) are at the symmetry positions (1 - x, 1 - y, 1 - z), (1 + x, y, z) and (-1 + x, y, z), respectively, and atoms Ca1*, Ca1# and Ca1$ are at the positions (½, ½, ½), ( $[3\over 2]$ , ½, ½) and (−½, ½, ½), respectively.
