Supporting information
To a solution of 6-chloro-3-pyridineacetic acid (1 mmol) in doubly-distilled water (60 ml ), a solution of an equimolar amount of sodium hydroxide in doubly-distilled water (40 ml) was added drop wise at room temperature. After vigorous stirring for 4 h, the resulting mixture was evaporated in vacuo to a volume of about 20 ml and filtered hot. The filtrate was then set aside for crystallization at room temperature. Two weeks later, colourless crystals of the title compound were isolated.
The H atoms were placed in geometrically idealized positions (O—H = 0.85, C—H = 0.93–0.97 Å) and treated as riding on their parent atoms, with Uiso(H) = 1.5Ueq(O) or Uiso(H) = 1.2Ueq(C).

Special details top Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In the title compound (Fig. 1), (I), the Na atom has a distorted O6 octahedral environment formed by a terminal water molecule O4, four O atoms derived from µ2-bridging water molecules and one carboxylate (O1) atom of the 6-chloro-3-pyridineacetate ligand (Table 1). Each coordination octahedron shares two O···O edges with two adjacent octahedra, thus producing infinite chains. Similar chains were found in the structure of sodium carboxynitrobenzoate tetrahydrate (Guo, 2004). In (I), the chains are linked into a three-dimensional network via O—H···O and O—H···N hydrogen bonds (Table 2 and Fig. 2).
