Poly[(μ(4)-pyridine-2,3-dicarboxyl-ato)lead(II)].

ABSTRACT: In the title coordination polymer, [Pb(C(7)H(3)NO(4))](n), the Pb(II) ion is eight-coordinated in a distorted square-anti-prismatic geometry formed by one pyridine N atom and seven carboxyl-ate O atoms from four pyridine-2,3-dicarboxyl-ate (pda) anions. In the pda anion, the dihedral angles between the pyridine ring and carboxyl-ate groups are 19.5 (6) and 73.3 (6)°. The carboxyl-ate groups of the pda anions bridge the Pb ions, forming a two-dimensional coordination polymer parallel to (100). Weak inter-molecular C-H⋯O hydrogen boning is present in the crystal structure.
