Poly[([mu]2-aqua-[kappa]2O:O)([mu]3-azido-[kappa]3N1:N1:N3)([mu]2-isonicotinato-[kappa]2O:O')lead(II)]

In the title compound, [Pb(C6H4NO2)(N3)(H2O)]n, the Pb ion is seven-coordinated by three N atoms from three azide ligands, two O atoms from two isonicotinate (inic) ligands and two O atoms from two coordinated water molecules, forming a distorted monocapped triangular prismatic coordination geometry. Each azide ligand bridges three PbII ions in a μ1,1,3 coordination mode to form a two-dimensional three-connected 63 topology network extending in the bc plane. The carboxylate group of the inic unit and the aqua ligand act as coligands to bridge PbII ions. Adjacent two-dimensional layers are connected by hydrogen-bonding interactions between the isonicotinate N atom and the water molecule, resulting in an extended three-dimensional network. The title complex is the first reported coordination polymer involving a p-block metal, an azide and a carboxylate. [PUBLICATION ABSTRACT]
