The title compound, [Pb2(C2O4)(NO3)2(C10H8N2)2(H2O)2], was synthesized hydrothermally. The binuclear complex molecule is centrosymmetric, the inversion centre being located at the mid-point of the oxalate C—C bond. The PbII ion is heptacoordinated by the O atom of one water molecule, two oxalate O atoms, two nitrate O atoms and two 2,2′-bipyridine N atoms, forming an irregular coordination environemnt. Intermolecular O—HO hydrogen bonds between water molecules and oxalate and nitrate ions result in the formation of layers parallel to (010). π–π interactions between pyridine rings in adjacent layers, with centroid–centroid distances of 3.584 (2) Å, stabilize the structural set-up.
