catena-Poly[[[diaqua(nitrato- #954;2O,O #8242;)cerium(III)]-bis[ #956;-2-(4-hydroxyphenyl)acetato]- #954;3O,O #8242;:O; #954;3O:O,O #8242;] monohydrate]

In the title compound, {[Ce(C8H7O3)2(NO3)(H2O)2]·H2O}n, the CeIII ion is coordinated by eight O atoms from four 2-(4-hydroxyphenyl)acetate (HPAA) ligands, two O atoms from the chelating nitrate anion and two water molecules in a distorted bis-capped quadrangular prismatic geometry. The HPAA ligands coordinate in a bridging tridentate mode. In the crystal, intermolecular O—H...O hydrogen bonds form a three-dimensional network which consolidates the packing.
