In the polymeric title compound, {[La(2)(C(7)H(3)NO(4))(2)(C(2)O(4))(H(2)O)(6)]·H(2)O}(n), the La(3+) cation is nine-coordinated in a distorted LaNO(8) tricapped trigonal–prismatic geometry formed by three pyridinedicarboxylate anions, one oxalate anion and three water molecules. The oxalate anion...

| description | In the polymeric title compound, {[La(2)(C(7)H(3)NO(4))(2)(C(2)O(4))(H(2)O)(6)]·H(2)O}(n), the La(3+) cation is nine-coordinated in a distorted LaNO(8) tricapped trigonal–prismatic geometry formed by three pyridinedicarboxylate anions, one oxalate anion and three water molecules. The oxalate anion is located on an inversion center. The oxalate and pyridinedicarboxylate anions bridge the La(3+) cations, forming a two-dimensional polymeric complex parallel to (010). Intermolecular O—H⋯O hydrogen bonding and weak C—H⋯O hydrogen bonding is present in the crystal structure and π–π stacking [centroid–centroid distance = 3.571 (3) Å] is observed between parallel pyridine rings of adjacent molecules. The uncoordinated water molecule shows an occupancy of 0.5. |
