Abstract:
In the title compound, 2Na(+)·C(9)H(3)NO(8) (2-)·3H(2)O, the asymmetric unit consists of two Na(+) cations, one dihydrogen pyridine-2,3,5,6-tetra-carboxyl-ate dianion (H(2)pdtc(2-)) and three water mol-ecules coordinated to the Na(+) cations. The configuration of the anion is stabilized by intramolecular O-H⋯O hydrogen bonding between vicinal carboxylate/carboxy groups. The Na(+) cations are bridged by the H(2)pdtc(2-) dianions, generating layers extending infinitely in sheets parallel to (001), and further pillared by the water mol-ecule linkers to build up a three-dimensional framework.
