Bottom Line: Four neighbouring Pb(II) atoms are bridged through two μ(3)-hydroxide ligands, forming the centrosymmetric Pb(4)(OH)(2) core.The three-dimensional structure is further achieved through bridging carboxyl-ate groups.There are also O-H⋯O hydrogen bonds between the hydroxide ligand and the carboxyl-ate group.

ABSTRACT
The asymmetric unit of the title coordination polymer, [Pb(2)(C(8)H(2)NO(6))(OH)](n), contains two crystallographically independent Pb(II) ions, one pyridine-2,4,6-tricarboxyl-ate (ptc) trianion and one hydroxide anion. One of the Pb(II) atoms is coordinated by one pyridine N and four carboxyl-ate O atoms from the ptc trianion and a hydroxide O atom in a distorted octa-hedral geometry. The other Pb(II) atom is five-coordinated by three carboxyl-ate O atoms and two hydroxide O atoms in a distorted tetra-gonal-pyramidal geometry. Four neighbouring Pb(II) atoms are bridged through two μ(3)-hydroxide ligands, forming the centrosymmetric Pb(4)(OH)(2) core. The three-dimensional structure is further achieved through bridging carboxyl-ate groups. There are also O-H⋯O hydrogen bonds between the hydroxide ligand and the carboxyl-ate group.
