Poly[triaquatris(μ4-pyridine-3,5-dicarboxylato)dicerium(III)]
The asymmetric unit of the title compound, [Ce2(C7H3NO4)3(H2O)3]n, contains two CeIII cations, three pyridine-3,5-dicarboxylate (pyd) anions and three coordinated water molecules. One CeIII cation is coordinated by seven carboxylate O atoms from six pyd anions and two water molecules in a square...

The asymmetric unit of the title compound, [Ce2(C7H3NO4)3(H2O)3]n, contains two CeIII cations, three pyridine-3,5-dicarboxylate (pyd) anions and three coordinated water molecules. One CeIII cation is coordinated by seven carboxylate O atoms from six pyd anions and two water molecules in a square-face-capped square-antiprismatic geometry. Another CeIII cation is coordinated by seven O atoms from six pdy anions and one water molecule in a bicapped trigonal–prismatic geometry. The pdy anions bridge the CeIII cations, forming the three-dimensional polymeric structure. The crystal structure contains extensive O—H⋯O, O—H⋯N and weak C—H⋯O hydrogen bonds. π–π stacking is present in the crystal structure, the shortest centroid–centroid distance between parallel pyridine rings being 3.509 (4) Å. |
