title: catena-Poly[[[aqua-[2-(6-chloro-pyridin-3-yl)acetato-κO]sodium]-di-μ-aqua] monohydrate].
abstract: The crystal structure of the title compound, {[Na(C(7)H(5)ClNO(2))(H(2)O)(3)]·H(2)O}(n), features polymeric chains along [010]. The Na(+) cation is octa-hedrally coordinated by four bridging water mol-ecules, a terminal water mol-ecule and an O atom derived from a monodentate carboxyl-ate ligand. Adjacent polyhedra share two O⋯O edges. The polymeric chains are linked into a three-dimensional network via O-H⋯O and O-H⋯N hydrogen bonds.
