Figure 16
Part of the crystal structure of (9) showing the formation of a 2₁ helical chain along (1, ½, z) built from only cations and water molecules. The atoms marked with an asterisk (*), a hash (#), a dollar sign ($) or an ampersand (&) are at the symmetry positions ( $[2 - x, 1 - y, -{1\over 2} + z]$ ), (x, y, -1 + z), ( $[2 - x, 1 - y, {1\over 2} + z]$ ) and (x, y, 1 + z), respectively.
