catena-Poly[[bis-(3-methyl-benzoato-κO,O')lead(II)]-μ-4,4'-bipyridine-κN:N'].

In the title complex, [Pb(C(8)H(7)O(2))(2)(C(10)H(8)N(2))](n), the Pb(II) atom is located on a twofold rotation axis and is six-coordinated by four carboxyl-ate O atoms from two 3-methyl-benzoate ligands and two N atoms from two 4,4'-bipyridine (4,4'-bpy) ligands, displaying a hemi-directed coordination. The 4,4'-bpy ligand has an inversion center at the mid-point of the central C-C bond. The Pb(II) atoms are linked by bidentate bridging 4,4'-bpy into a chain along [101]. These chains are further connected into layers via C-H⋯O hydrogen bonds.
