In the title compound, [Na(C10H9O6)(C10H10O6)]·0.5C10H8N2·H2O, the Na atom is eight-coordinated in an distorted dicapped-octahedral geometry by eight O atoms from a 2-(2-carboxymethoxyphenoxy)acetate (o-BDOAH) anion and a 2,2'-(o-phenylenedioxy)diacetic acid (o-BDOAH2) molecule. The uncoordinated 4,4'-bipyridine molecule is arranged around an inversion center and exhibits rotational disorder. A three-dimensional supramolecular network is built up in the crystal through O-HO and O-HN hydrogen bonds between the uncoordinated water molecule, the uncoordinated 4,4'-bipyridine molecule and the sodium complex molecule.
