Figure 2
The polymeric chain in (I), showing the helical arrangement of Zn1 and S1 atoms. For clarity, only one example of the intrachain hydrogen bond has been shown in the upper part of the polymer helix. The hydrogen bonds are indicated by dashed lines and numbered according to the order of their appearance in Table 1.
