Figure 6
Part of the crystal structure of compound (II), showing the π–π stacking interaction which generates chains along [101]. For the sake of clarity, the H atoms, the solvent molecules and the unit-cell outline have been omitted. Atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions (x + , y, z + ) and (x + 1, y, z + 1), respectively. |
