Figure 3 The packing diagram of the title compound, showing intermolecular π–π interactions (dashed lines) between the pyridine rings of the pydc ligands [centroid–centroid distance = 3.4575 (15) Å] and between the benzene rings of the (bdaH2)2+ cations and the pyridine rings of the pydc ligands [centroid–centroid distance = 3.7521 (15) Å]. Water molecules have been omitted for clarity. |
