Figure 6
The supramolecular structure of (IIB), showing (a) the layer parallel to the ab plane and (b) the interactions between two neighbouring layers (blue and pink) viewed parallel to the c axis, with the DMF molecules shown in space-filling style. Green dashed lines represent C—H⋯Cl hydrogen bonds and dark dashed lines represent π–π stacking. All H atoms, except those involved in hydrogen-bonding interactions, have been omitted for clarity.
