Figure 1
A view of the asymmetric unit of (I)[link], showing the atom-numbering scheme for the repeat unit of molecules (Ia) and (Ib). Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. Dashed lines represent the superimposed N11—H11⋯H43 and N43—H43⋯N11 hydrogen bonds.
