|
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 PbII atom is six-coordinated by four O atoms and two N atoms of two tridentate pyridine-2,6- dicarboxylic acid molecules. Intermolecular N—H O and O—H O 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.
