Sodium 5-nitro-2-pyridonate trihydrate
The title compound, alternatively sodium pyridin-2-olate trihydrate, Na(+).C(5)H(3)N(2)O(3)(-).3H(2)O, crystallizes in the P-1 space group. It is made up of edge-shared chains of NaO(6) octahedra with five water molecules and one 5-nitro-2-pyridonate anion. Four of these water molecules are bicoordinating, involved in connecting the adjacent octahedra, and the fifth is coordinated to only one octahedron. The crystal structure is stabilized by a network of strong O-H.O and O-H.N interactions. The organic moieties occupy the space between the chains with an antiparallel alignment.
