abstract: In the tetranuclear centrosymmetric title compound, [Pb(4)(NO(3))(8)(C(11)H(10)N(2))(4)], irregular PbN(2)O(5) and PbN(2)O(4) coordination polyhedra occur. The hepta-coordinated lead(II) ion is bonded to two bidentate and one monodentate nitrate ion and one bidentate 6-methyl-2,2'-bipyridine (mbpy) ligand. The six-coordinate lead(II) ion is bonded to one bidentate and two monodentate nitrate anions and one mbpy ligand. In the crystal, bridging nitrate anions lead to infinite chains propagating in [111]. A number of C-H⋯O hydrogen bonds may stabilize the structure.
