Figure 2
Fragment of the extended sheet in I lying parallel to the (01) plane. C-bound H atoms, N2 pyridine rings, water molecules of crystallization and minor occupancy components B of the disordered carboxylate groups have been omitted for clarity. Hydrogen-bonding interactions are shown as black dotted lines, π–π stacking interactions between benzene rings in double chains and those between coordinated N1 pyridine molecules are shown as lilac and green bold lines, respectively. Symmetry code: (i) –x + 1, –y + 1, –z + 2. |
