In the title compound, (C3H12N2)[Hg(C7H3NO4)2]·2H2O, the HgII ion is coordinated by four O and two N atoms of two pyridine-2,6-dicarboxylate (pydc) ligands in a distorted octahedral environment. The structure contains two uncoordinated water molecules. In the crystal, N—H⋯O, O—H⋯O and weak C—H⋯O hydrogen bonds and π–π stacking interactions between the pyridine rings of the pydc ligands, with a centroid–centroid distance of 3.4582 (18) Å, stabilize the structure.
