Figure 8
Part of the crystal structure of compound (IV), showing the π–π stacking interaction which links hydrogen-bonded chains along [001] into a sheet parallel to (100). The original atomic coordinates (Fun et al., 2012) have been used. For the sake of clarity, the H atoms, the solvent molecules and the unit-cell outline have been omitted. The atom marked with an asterisk (*) is at the symmetry position (−x, −y, −z). |
