Di-μ-aqua-bis­{triaqua­[5-(1-oxopyridin-4-yl)tetra­zol-1-ido]sodium}

In the title compound, [Na2(C6H4N5O)2(H2O)8], the NaI atom is in a distorted octahedral environment defined by six O atoms, one from the 5-(1-oxopyridin-4-yl)tetra­zolide anion and five from water mol­ecules. Two water mol­ecules act as bridging ligands, resulting in the formation of dimeric units organized around inversion centers. In the organic anion, the pyridine and tetra­zole rings are nearly coplanar, forming a dihedral angle of 4.62 (1)°. The dimeric units and organic anions are connected by O—H⋯O and O—H⋯N hydrogen bonds, leading to the formation of a three-dimensional network.
