title: μ-4,4'-Bipyridine-κN:N'-bis-[bis-(2-chloro-benzoato-κO,O')lead(II)].
abstract: In the title dinuclear complex, [Pb(2)(C(7)H(4)ClO(2))(4)(C(10)H(8)N(2))], the Pb(II) atom is five-coordinated by four carboxyl-ate O atoms from two 2-chloro-benzoate ligands and one N atom from a bridging 4,4'-bipyridine (4,4'-bpy) ligand, 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 empty side of the metal ion is capped by two carboxyl-ate O atoms from a neighboring mol-ecule, with weak Pb⋯O contacts [Pb⋯O = 3.069 (2) and 3.071 (3) Å]. The crystal structure is stabilized by C-H⋯O hydrogen bonds and π-π stacking inter-actions between the benzene and pyridine rings [centroid-centroid distance = 3.749 (3) Å].
