Poly[(mu2-aqua-kappa2O:O)(mu3-azido-kappa3N1:N1:N3)(mu2-isonicotinato-kappa2O:O')lead(II)].
In the title compound, [Pb(C(6)H(4)NO(2))(N(3))(H(2)O)](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 Pb(II) ions in a mu(1,1,3) coordination mode to form a two-dimensional three-connected 6(3) topology network extending in the bc plane. The carboxylate group of the inic unit and the aqua ligand act as coligands to bridge Pb(II) 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.
