Abstract:
The Pb(II) cation in the title compound, [Pb(2)(C(14)H(4)N(2)O(8))](n), is seven-coordinated by one N atom and six O atoms from four 4,4'-bipyridine-2,2',6,6'-tetracarboxylate (BPTCA(4-)) ligands. The geometric centre of the BPTCA(4-) anion lies on an inversion centre. Each pyridine-2,6-dicarboxylate moiety of the BPTCA(4-) ligand links four Pb(II) cations via its pyridyl N atom and two carboxylate groups to form two-dimensional sheets. The centrosymmetric BPTCA(4-) ligand then acts as a linker between the sheets, which results in a three-dimensional metal-organic framework.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
