?-Adipato-?O:O-bis-{[2,6-bis-(1H-benzimidazol-2-yl-?N)pyridine-?N](nitrato-?O)lead(II)}.


ABSTRACT: The dinuclear title compound, [Pb(2)(C(6)H(8)O(4))(NO(3))(2)(C(19)H(13)N(5))(2)], lies with the mid-point of the butyl chain of the bridging adipate unit on a center of inversion. The Pb(II) ion is covalently bonded to the nitrate anion and is bonded to a carboxyl-ate group of the adipate unit by another covalent bond. The N-heterocycle functions in a chelating tridentate mode. The metal atom exists in a ?-octa-hedral coordination environment. When weaker Pb?O inter-actions are also considered, the geometry is a ?-tricapped trigonal prism in which the lone-pair electrons occupy one face of the trigonal prism. Adjacent mol-ecules are linked into a layer structure by N-H?O hydrogen bonds.
