title: {2-[2-(Carb-oxy-meth-oxy)-phen-oxy]acetato}[2,2'-(o-phenyl-enedi-oxy)diacetic acid]sodium 4,4'-bipyridine hemisolvate monohydrate.
abstract: In the title compound, [Na(C(10)H(9)O(6))(C(10)H(10)O(6))]·0.5C(10)H(8)N(2)·H(2)O, the Na atom is eight-coordinated in an distorted dicapped-octa-hedral geometry by eight O atoms from a 2-(2-carb-oxy-meth-oxy-phen-oxy)acetate (o-BDOAH) anion and a 2,2'-(o-phenyl-enedi-oxy)diacetic acid (o-BDOAH(2)) mol-ecule. The uncoordinated 4,4'-bipyridine mol-ecule is arranged around an inversion center and exhibits rotational disorder. A three-dimensional supra-molecular network is built up in the crystal through O-H⋯O and O-H⋯N hydrogen bonds between the uncoordinated water mol-ecule, the uncoordinated 4,4'-bipyridine mol-ecule and the sodium complex mol-ecule.
