| Popis: | In the polymeric title compound, {[Ce2(C7H3NO4)2(C2O4)(H2O)6]·H2O}n, the Ce3+ cation is nine-coordinated in a distorted CeNO8 tricapped trigonal–prismatic geometry, formed by three pyridine-2,4-dicarboxylate anions, one oxalate anion and three water molecules. The mid-point of the oxalate anion is located on an inversion center. The oxalate and pyridine-2,4-dicarboxylate anions bridge the Ce3+ cations, forming a two-dimensional polymeric complex parallel to (010). Intermolecular classical O—H...O hydrogen bonding and weak C—H...O hydrogen bonding are present in the crystal structure and π–π stacking [centroid–centroid distance = 3.558 (2) Å] is observed between parallel pyridine rings of adjacent molecules. The uncoordinated water molecule shows an occupancy of 0.5. |
