Figure 2
A packing diagram for (I). The helices of the hydrogen tartrate anions run parallel to the crystallographic b axis. For clarity, bonds in the tolterodinuim cation are shown as solid and those in the tartrate anion are shown as open. Atoms marked with an asterisk (*) or hash (#) are at the symmetry positions (1 − x, + y, 1 − z) and (2 − x, + y, −z), respectively. |
