Abstract: The asymmetric unit of the title compound, (C₄H₁₂N₂)[Pb(C₇H₃NO₄)₂]·2H₂O, contains two half-cations, one anion and two water molecules. There is a centre of symmetry at the centre of each cation ring. The Pb^II atom is six-coordinated by four O atoms and two N atoms of two tridentate pyridine-2,6-dicarboxylic acid molecules. Intermolecular N-HO and O-HO hydrogen bonds and - stacking interactions seem to be effective in the stabilization of the crystal structure, resulting in the formation of a three-dimensional network.
