catena-Poly[[{diaqua­[2-(4-hy­droxy­phen­yl)acetato-κ(2) O,O′]cerium(III)}-bis­[μ-2-(4-hy­droxy­phen­yl)acetato]-κ(3) O,O′:O;κ(3) O:O,O′] 4,4′-bipyridine disolvate monohydrate]

In the polymeric title complex, {[Ce(C(8)H(7)O(3))(3)(H(2)O)(2)]·2C(10)H(8)N(2)·H(2)O}(n), the Ce(III) ion is coordinated by ten O atoms from four 2-(4-hy­droxy­phen­yl)acetate (HPAA) ligands and two water mol­ecules. One HPAA ligand coordinates just to one Ce(III) ion, whereas the remaining two bridge two Ce(III) ions. The 4,4′-bipyridine mol­ecule and one water mol­ecule are not coordinated to Ce. In the crystal, O—H⋯O and O—H⋯N hydrogen bonds link mol­ecules into a three-dimensional network.
