Abstract:
The title compound, [Pb(2)(C(2)O(4))(NO(3))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], was synthesized hydro-thermally. The binuclear complex mol-ecule is centrosymmetric, the inversion centre being located at the mid-point of the oxalate C-C bond. The Pb(II) ion is hepta-coordinated by the O atom of one water mol-ecule, two oxalate O atoms, two nitrate O atoms and two 2,2'-bipyridine N atoms, forming an irregular coordination environemnt. Inter-molecular O-H⋯O hydrogen bonds between water mol-ecules and oxalate and nitrate ions result in the formation of layers parallel to (010). π-π inter-actions between pyridine rings in adjacent layers, with centroid-centroid distances of 3.584 (2) Å, stabilize the structural set-up.
