| Popis: | In the title complex, [Pr(C9H4N2O4)(C2H3O2)(H2O)]n, the PrIII ion is coordinated by five O atoms and one N atom from four benzimidazole-5,6-dicarboxylate ligands, two O atoms from an acetate ligand and one water molecule, giving a tricapped trigonal-prismatic geometry. The benzimidazole-5,6-dicarboxylate and acetate ligands connect the PrIII ions, forming a layer in the ac plane; the layers are further linked by N—H...O and O—H...O hydrogen bonding and π–π stacking interactions between neighboring pyridine rings [the centroid–centroid distance is 3.467 (1) Å], assembling a three-dimensional supramolecular network. The acetate methyl group is disordered over two positions with site-occupancy factors of 0.75 and 0.25. |
