Disodium dihydrogen pyridine-2,3,5,6-tetra­carboxyl­ate trihydrate

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-tetra­carboxyl­ate dianion (H(2)pdtc(2−)) and three water mol­ecules coordinated to the Na(+) cations. The configuration of the anion is stabilized by intramole...

Descripción
Sumario: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-tetra­carboxyl­ate dianion (H(2)pdtc(2−)) and three water mol­ecules 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 mol­ecule linkers to build up a three-dimensional framework.
