Figure 2
The polymeric structures formed via O—H⋯N hydrogen bonds in the two polymorphs of DABCO monohydrate. (a) Top and side views of the 31 helix in polymorph (II). (b) Top and side views of the chain in (I). N and O atoms are represented as spheres. H atoms, except those of the water molecules, have been omitted for clarity. Only one orientation for each disordered DABCO molecule is shown. Hydrogen bonds are shown as dotted lines. |
